Diabetes affects millions of people every year. Blood vessels located all over the body are damaged due to diabetes—even the blood vessels of the feet. Neuropathy, or nerve damage, can result from slower blood flow in the legs and feet. In diabetic patients, neuropathy is very important to monitor, as diabetics are at risk for developing ulcers.
Always washing and thoroughly drying the feet are pertinent parts of diabetic foot care. There should be a focus on cleaning between the toes. Even if no pain is felt, the entire foot should be examined for redness and sores. Neuropathy can often mask the pain of sores and ulcers and can cause these conditions to be overlooked. Use a mirror to examine the underside of your feet if needed. It is recommended that diabetics wear well-fitting socks.
Patients with diabetes should have their doctor monitor their blood levels because blood sugar levels play a huge role in diabetic care. Monitoring these levels on a regular basis is highly advised. It is very important to keep your blood sugar levels in the normal range, which can be determined by your physician. There are medications that may be prescribed to help with any neuropathy experienced by the diabetic patient. It is also advisable to visit a podiatrist if one is experiencing any conditions involving the feet, such as ingrown toenails, which in more severe cases can cause infection.
Diabetic feet must be inspected daily. Diabetic foot care at home is possible if a patient is provided with instructions from their podiatrist. Patients can relieve dry heels with creams or ointments. Suspected wounds should warrant an immediate call to the podiatrist. Gangrene is a serious problem for diabetics and can lead to sepsis and amputation in its worst cases. Early treatment and daily inspection of diabetic feet are keys to staying healthy.
Ankle sprains occur when ligaments that support the ankle stretch beyond their limits and tear. These types of injuries are very common and can occur in people of all ages. Sprains may range from mild to severe, depending on how much damage is done to the ligaments. If a sprain goes untreated, a more severe sprain may occur which can further damage the ankle. Repeated ankle sprains can lead to chronic ankle pain.
There are some risk factors that can increase your risk of suffering a sprained ankle. Those who participate in sports, walk on uneven surfaces, have a prior ankle injury, are in poor physical condition, or wear improper shoes are more likely to get a sprained ankle.
There are a few symptoms to look out for if you suspect you are suffering from a sprained ankle. Some common symptoms are swelling, bruising, tenderness, and instability of the ankle. In cases where the tearing of the ligaments is severe, there may be a “popping” sound when the strain occurs.
The RICE method is proven to be effective in treating ankle sprains. RICE stands for Rest, Ice, Compression, and Elevation. Rest is important for treatment, especially within the first 24 to 48 hours. You should also ice your sprained ankle for the first 48 hours for 20 minutes at a time. A small piece of cloth should be placed between the ice and the affected area. For the compression step, you should wear a brace that is snug, but not too tight that it cuts off circulation. When choosing a brace, be sure to choose one that is suitable for the type of ankle sprain you have. Lastly, you should elevate your foot above the heart as often as possible.
After you treat a sprain, you should go through rehabilitation to prevent the injury from occurring again. There are three phases to the rehab process. The first phase involves resting, protecting, and reducing the swelling of the injury. The second phase consists of restoring the ankle’s flexibility, range of motion, and strength. The third phase consists of slowly returning to activity and maintenance exercises.
If you suspect you have an ankle sprain, you shouldn’t hesitate to consult with your podiatrist. Your podiatrist will be able to give you a proper diagnosis and a suitable treatment option for your condition.
Biomechanics and its related study deal with the forces that act against the body and affect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot, as well as the forces that impact them. Podiatrists who train in this specialty are able to effectively diagnose and treat conditions that affect people’s everyday movement.
Regardless of your lifestyle, age, or any other factors, many people experience foot problems throughout their lives. Twists and turns, improper balance, and added weight are just a few of the things that can add stress to the feet. These issues can also limit our bodies’ mobility that we often take for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area. This affects the way you move around on a daily basis.

The history of studying biomechanics dates back to ancient Egypt at around 3000 B.C., where evidence of professional foot care has been recorded. Throughout the centuries, advances in technology, science, and an understanding of the human body led to more accurate diagnosis of conditions such as corns for example. In 1974, biomechanics garnered a large audience when Merton Root founded Root Lab to make custom orthotics. He proposed that corrections of certain conditions could be implemented to gain strength and coordination in the area. Due to his research, we still use his basic principle of foot orthotics to this day.
As technology has improved, so have the therapeutic processes that allow us to correct deficiencies in our natural biomechanics. Computers can now provide accurate readings of the forces, movements, and patterns of the foot and lower leg. Critical treatment options can be provided to patients now who suffer from problems that cause their biomechanics to not function naturally. The best results are now possible thanks to 3D modeling and computing technologies that can take readings and also map out what treatment will do to the affected areas.
These advanced corrective methods were able to come to light thanks to an increase in both the technologies surrounding biomechanics and also the knowledge of how they work naturally. For example, shoe orthotics are able to treat walking inabilities by realigning the posture deviations in patients caused by hip or back problems. Understanding foot biomechanics can help improve movement and eliminate pain, stopping further stress to the foot. Speak with your podiatrist if you have any of these problems.
A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.
Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.
A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.
Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.
For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.
Although rheumatoid arthritis attacks multiple bones and joints throughout the entire body, ninety percent of people who actually develop this condition usually do so in the foot or ankle area. Those who develop this kind of arthritis in the feet usually develop symptoms around the toes and forefeet first, before anywhere else. Rheumatoid arthritis appears to have a genetic component. If it runs in the family, then you will be more likely to develop it as well.
Rheumatoid arthritis is an autoimmune disorder in which the body’s own immune system attacks the lining of the membranes surrounding the joints. This causes inflammation of the membrane lining, and the gradual destruction of the joint’s cartilage and even bone.
Some of the most common symptoms that are associated with RA include pain and swelling of the feet. Stiffness in the feet is also another common symptom that people experience. Those who have RA in the feet usually feel the pain in the ball or sole of their feet. This can get to be very painful at times. A person's joints can even shift and become deformed after a period of time.
In order to properly diagnose RA in the feet it is usually necessary for a doctor or podiatrist to evaluate the area. Your doctor will also question you about your medical history, occupation, etc., to determine whether anything in your lifestyle may have triggered the condition. There are a number of tests that may be performed to help diagnose RA, such as a rheumatoid factor test. There is, however, no one single test that will tell you for sure if you have RA. There are different X-rays that can be taken as well to determine if a person has RA in their feet.
There is a range of treatment options for rheumatoid arthritis. Treatment of RA is usually a lifelong process that includes a variety of methods of treatment and therapy. Your doctor can prescribe special shoes that should help with arch support as well as heel support. A physical therapist can help those with this condition learn exercises which will keep their joints flexible. Surgery may be needed to correct some of the issues with the feet, such as bunions, and hammertoes. Fusion is usually the most successful surgical option for rheumatoid arthritis. However, people need to keep in mind that there are some risks associated with these surgeries.
Foot and ankle injuries are common among athletes and those who exercise frequently. Most of these injuries are non-life-threatening and can heal in weeks with proper treatment and care. Serious injuries, however, require urgent medical treatment.
Common minor injuries include ankle sprains, ankle strains, Achilles tendonitis, plantar fasciitis, stress fractures, and turf toe. An ankle sprain is when the ligaments in the ankle have either become stretched or torn. When the muscle or tendon is stretched or torn, it is an ankle strain. When the big toe is sprained, it is known as turf toe. Achilles tendonitis is the overuse and inflammation of the Achilles tendon. Plantar fasciitis is the inflammation of the plantar fascia and generally occurs from overuse in athletics. Stress fractures are also caused from overuse and are small cracks in the bone.
Achilles tendon ruptures are common, but more serious. This injury occurs when the Achilles tendon, the largest tendon in the body, ruptures. In most cases, this causes severe pain and difficulty walking; some who have experienced this injury have reported, however, no signs or symptoms. A laceration is a deep cut that can occur anywhere on the body. Lacerations on the foot are rarer, but can occur from things like metal cleats landing on the foot.
Treatment options cover a wide range of methods based upon the injury and its severity. Conditions like plantar fasciitis, stress fractures, Achilles tendonitis, turf toe and ankle sprains/ strains can heal on their own without immediate medical care, but seeing a podiatrist to monitor the injury is always recommended. Following the RICE (Rest, Icing, Compression, and Elevation) protocol is generally enough to treat minor injuries. This means resting the foot by either keeping pressure off the foot or not walking at all. Icing the injury will help reduce swelling and pain. Compressing the wound with a wrap will immobilize and help promote healing. Finally, keeping the wound elevated will also reduce swelling and also help the healing process.
It is important to note that even minor injuries can vary in severity, with grade one being a minor injury and grade three requiring urgent care by a podiatrist. Achilles tendon ruptures and lacerations on the foot generally require urgent medical care and treatment options that need a podiatrist. These could include imaging tests, stitches for cuts, rehabilitation, and casts or braces. Every case is different, however, so it is always recommended to see a podiatrist when pain in the foot does not disappear.
Heel spurs are the result of calcium deposits that cause bony protrusions on the underside of the heel. Heel spurs are usually painless, but they have the potential to cause heel pain. Heel spurs tend to be associated with plantar fasciitis, which is a condition that causes inflammation of the band of connective tissue that runs along the bottom of the foot. They most often occur to athletes whose sports involve a lot of running and jumping.
Some risk factors for developing heel spurs include running and jogging on hard surfaces, being obese, wearing poorly fitting shoes, or having walking gait abnormalities.
It is possible to have a heel spur without showing signs of any symptoms. However, if inflammation develops at the point of the spur’s formation, you may have pain while walking or running. In terms of diagnosis, sometimes all a doctor needs to know is that the patient is experiencing a sharp pain localized to the heel to diagnose a heel spur. Other times, an x-ray may be needed to confirm the presence of a heel spur.
Heel spurs can be prevented by wearing well-fitting shoes that have shock-absorbent soles. You should also be sure that you are choosing the right shoe for the activity you want to partake in; for example, do not wear walking shoes when you want to go on a run. Additionally, maintaining a healthy weight can be beneficial toward preventing heel spurs, as it will prevent an excess amount of pressure being placed on the ligaments.
There are a variety of treatment options for people with heel spurs. Some of these include stretching exercises, physical therapy, shoe inserts, or taping and strapping to rest stressed muscles and tendons. If you have heel pain that lasts longer than a month, don’t hesitate to seek help from a podiatrist. Your doctor can help you determine which treatment option is best for you.
Corns are thickened areas on the skin’s surface, to the point of being irritating and sometimes painful. Commonly found on the feet, corns are circular or cone-shaped. They develop where there are areas of pressure or friction, such as on the little toe when it rubs up against shoes, or on the ball of your foot.
Corns are often confused with a callus, but there is a difference between them. Corns can be raised bumps that are painful to the touch. They consist of a rough, thick area of skin that may be dry or waxy. Corns tend to be surrounded by skin that is inflamed, and are usually much smaller than calluses.
Removing the dead skin that has built up is the key in treating corns. Salicylic acid medication is most common in accomplishing this. The acid works by dissolving keratin, which is the protein that makes up the majority of corns. You can purchase salicylic acid over-the-counter in products such as wart removers. It comes in a variety of forms such as medicated pads, drops, or creams. However, people who are diabetic should not use salicylic acid, but should instead consult their doctor immediately.
According to the product directions, applying the medication directly onto the corn will treat it. The top layer of the corn will begin to turn white after use. When that occurs, the layers of skin can then be peeled away, making the corn smaller. Shaving off corns with razors or other pedicure equipment is never a good idea. This can lead to infection. If your corn gets infected, and is not treated immediately, a visit to the doctor will be necessary.
Another way to treat corns and help prevent their return is by using orthotic inserts, fitted by a podiatrist. Inserts fit right into your shoes and adjusts the way your foot fits into your shoes. This fixes the way you walk. This will lower your chances of getting corns, and eliminate current corns by reducing rubbing from friction.
Surgery is rarely used to treat corns, but does occur on occasion. Surgery actually deals with the underlying issue that causes corns. During surgery, the bone is shaved and any abnormalities are corrected, thus reducing the amount of friction that occurs during walking.
To prevent corns, the first step is reducing friction. Always wear shoes that fit well and don’t rub your feet. Pads can be purchased if you notice rubbing developing. These pads can be purchased over-the-counter, and can be simply placed on the irritated area. Wearing cushioned insoles in your shoes can always reduce the friction, and making sure to wear well-fitting shoes. This will ensure that your foot is not being squeezed awkwardly, and prevent corns from forming in the first place.
Obesity is a common problem in American society. Approximately one third of the U.S. population is obese. Obesity is defined as a body mass index greater than 30. Obesity has the power to affect different aspects of the body, and one of the most common problems it causes is foot pain. There have been many studies that found a connection between an increased BMI and foot problems. A simple activity such as walking up a flight of stairs can increase pressure on the ankle by four to six times.
Being overweight causes the body to compensate for the extra weight by changing the way it moves. Consequently, people who struggle with obesity commonly have arch problems in their feet. Obesity causes the arch to break by stretching the ligaments and tendons that hold the bones in the foot together. When the arch lowers, the foot may eventually fall flat. Collapsed foot arches fail to provide adequate shock absorption which eventually leads to foot pain. Other conditions that may be caused by flat feet are pronation, plantar fasciitis, weak ankles, and shin splints.
Foot problems that are caused by obesity may be treated by wearing proper footwear. Proper shoes will allow your feet to have better circulation around the arch and ankle. Additionally, those with obesity often discover that typical heel pain remedies are not effective for them. They will find that their plantar fascia is easily injured, and it is often inflamed. The best way to treat this problem is to implement lifestyle changes. A few good ways to improve your diet are to reduce calories, fill up on fruits and veggies, and to limit sugars.
Custom foot orthotics can prevent foot problems if you’re carrying excess weight or are trying to lose weight. The purpose of orthotics is to provide shock absorption to decrease the amount of stress on the joints to prevent arthritis.
Hyperhidrosis of the feet, also termed plantar hyperhidrosis, is characterized by excessive sweating of the feet that can be onset by any cause, such as exercise, fever, or anxiety. Most people suffering from hyperhidrosis of the feet also experience hyperhidrosis of the hands, or palmar hyperhidrosis. Approximately 1-2% of Americans suffer from this disorder.
Sweating is a healthy process utilized by the body in order to cool itself and maintain a proper internal temperature, which is controlled by the sympathetic nervous system. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than is actually needed.
Plantar hyperhidrosis is considered primary hyperhidrosis. Secondary hyperhidrosis refers to excessive sweating that occurs in an area other than the feet, hands, or armpits, and this indicates that is related to another medical condition, such as menopause, hyperthyroidism, or Parkinson's disease.
Symptoms of hyperhidrosis of the feet can include foot odor, athlete's foot, infections, and blisters. Because of the continual moisture, shoes and socks can rot which creates an additional foul odor and can ruin the material, requiring shoes and socks to be replaced frequently. In addition to the physical symptoms, emotional health is often affected as this disorder can be very embarrassing.
If left untreated, hyperhidrosis will usually persist throughout an individual's life. However, there are several treatment options available. A common first approach to treating hyperhidrosis of the feet is a topical ointment. Aluminum chloride, an ingredient found in antiperspirants, can be effective at treating hyperhidrosis if used in high concentration and applied to the foot daily. Some individuals can experience relief this way, while others encounter extreme irritation and are unable to use the product. Another procedure is the use of Botulinum Toxin A, commonly referred to as Botox. This is injected directly into the foot, and is effective at minimizing the sweat glands in the injected area. These injections must be repeated every 4 to 9 months.
If these treatments are ineffective, oral prescription medications may be taken in an effort to alleviate the symptoms. Again, some will experience relief while others do not. Going barefoot reportedly provides relief for most sufferers.
A final approach to combating hyperhidrosis of the feet is through surgery. Surgery has been less successful on patients with plantar hyperhidrosis than on those with palmar hyperhidrosis. It is only recommended when sweating is severe and other treatments have failed to work. This kind of surgery usually involves going into the central nervous system, and cutting nerves to stop the transmission of signals telling the foot to sweat.
