Foot and ankle injuries are common among people who participate in sports. Several factors contribute to this. They include failing to stretch or warm up properly, not wearing the proper type of shoe and not taping or providing other types of support for the ankle or foot. The most common foot and ankle injuries suffered by people involved in sports are plantar fasciitis, ankle sprains and Achilles tendon damage or ruptures. If not treated properly, they can lead to permanent disability.
Treating these injuries is relatively simple if they are identified and addressed early. Many athletes dismiss the initial aches and pains associated with injury as just soreness or tired muscles. Their first response is usually to try to work through it. This can lead to serious problems. Many minor injuries are made far more serious when athletes continue to put strain and pressure on them. That attitude can change a mild strain into a serious strain and a minor tear into a rupture. Athletes should have unusual aches and pains evaluated by a skilled medical professional.
Plantar fasciitis is a painful injury. It is inflammation of the plantar fascia, the thick band of tissue running from the heel to the base of the toes. If left untreated, it can lead to a degenerative disease called plantar fasciosis. There are several effective treatments for this ailment. Doctors often prescribe rest, massages, stretching, night splints, physical therapy, anti-inflammatory medication, corticosteroids or surgery, usually in that order. The most effective treatment for plantar fasciitis is orthotics, which offers foot support. Surgery is occasionally used as a last resort, but it comes with the risk of nerve damage and infection and often does not stop the pain.
The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel bone. Running, jumping and walking all impact this tendon. Two common injuries to the Achilles tendon are tendonitis and a rupture of the tendon. Tendonitis is inflammation in the tendon often caused by an increase in the amount of stress placed on it. Non-surgical treatments include rest, ice or anti-inflammatory medication. A rupture (tear) of the Achilles tendon can be treated by placing the lower leg in a cast for several weeks or with surgery. Many physicians feel surgery is the better option because it lowers the risk of re-ruptures. Both methods require 4 to 6 months of rehabilitation.
Ankle sprains are the most common sports related foot and ankle injury. A sprain occurs when the ligament holding the ankle bones and joint stretches beyond its normal range. It can be treated non-surgically with a combination of rest, ice wrapped around the joint for 30 minutes immediately after injury, compression by a bandage and elevating the ankle above the heart for 48 hours. This combination is referred to as RICE. Severe ankle sprains in which the ligaments are torn may require reconstructive surgery followed by rehabilitation.
Each foot, on average, has about 250,000 eccrine sweat glands that produce half a pint of sweat each day. Sweating is a natural and important bodily function. It regulates the body’s temperature by cooling the skin so that it does not overheat. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than what is required. People with plantar hyperhidrosis experience an excess amount of sweat on their feet. It is estimated that 2% to 3% of all Americans suffer from some form of hyperhidrosis. This condition is often caused by neurologic, endocrine, infectious, and other systemic disease. Other factors that may trigger the condition are heat and emotions.
People with hyperhidrosis may notice an overabundance of sweat on their feet, along with a strong odor. The feet may also have a wet appearance coupled with infections such as athlete’s foot or toenail fungus. The sweat may even appear in low temperatures, such as during the winter months. People with plantar hyperhidrosis often need to change their socks several times throughout the day.
The specific cause of hyperhidrosis is unknown, and many believe it may be caused by over-activity. However, others believe the condition is genetic. Caffeine and nicotine are known to cause excitement and nervousness which are two emotions that may make the condition worse.
If you are looking to treat your hyperhidrosis the most important thing you should do is wash your feet every day. You may even need to wash your feet twice a day, if necessary. You should also make sure you are wearing the right socks. Wool and cotton socks are both known to be good for ventilation, meaning they allow the feet to breathe. You should avoid socks made from nylon which trap moisture and lead to sogginess. Other common treatment options are over-the-counter antiperspirants that contain a low dose of metal salt. In some cases, prescription strength antiperspirants that contain aluminum chloride hexahydrate may be necessary. In severe cases, surgery may be required.
Untreated hyperhidrosis can easily lead to complications. Some complications that may arise from the disorder include nail infections, warts, and bacterial infections. Consequently, it is important that you seek treatment from your podiatrist if you suspect that you may have plantar hyperhidrosis.
When conservative, noninvasive methods prove ineffective, surgery may be selected as the next course of action for the treatment of your foot or ankle condition. A wide number of foot and ankle surgical procedures exist, and it is up to your podiatrist to determine which intervention will be most appropriate and helpful for your case. Some surgical procedures include bunion surgery, fusion, hammertoe surgery, heel spur surgery, metatarsal surgery, nail surgery, neuroma surgery, reconstructive surgery, skin surgery, and tendon surgery. Typically, surgery is turned to as a definitive way to alleviate excessive pain or discomfort and to return your foot to full mobility.
Regardless of the location on the body, all surgical procedures require preoperative testing and examination to ensure the surgery’s success and preferred outcome. A review of your medical history and medical conditions will take place, as will an evaluation of any current diseases, illnesses, allergies, and medications. Tests such as blood studies, urinalyses, EKG, X-rays, and blood flow studies may be ordered. Because the procedure involves the foot and/or ankle, the structures of your feet while walking may also be observed by your podiatrist.
Care post-surgery will depend on the type of surgical procedure performed. Typically, all postoperative care involves rest, ice, compression, and elevation. To improve and ensure a safe recovery, your foot and ankle surgeon may also employ the use of bandages, splints, surgical shoes, casts, crutches, or canes. He will also determine if and when you can bear weight. A timely and thorough recovery is a priority for both you and your podiatrist, and carefully following postoperative instructions can help achieve this.
Blisters are a common ailment of people who wear shoes that are either too tight or rub against the feet in an uncomfortable way. Knowing the basics of blisters is important for understanding how they are formed and what treatments should be used for them.
A blister on the foot, or any other part of the body, is a small pocket that is filled with fluid. It usually forms on the upper layer of the skin because these layers are loose enough to allow a blister to form. The most common fluid in a blister is just a clear, watery-like fluid that usually isn’t cause for concern. However, blisters can fill up with blood if they are deep enough and pus if they have become infected with bacteria.
Blisters almost always form on the feet due to shoes rubbing up against the foot, where the friction causes blisters. These can occur after you have walked for a long period of time or when your shoes do not fit you properly. Your feet are also more prone to blisters if they are moist, so keeping them dry and clean is one preventative step you can take.
Preventing infection should be the number one concern when treating blisters, as well as relieving the pain they can cause. Using a bandage to cover up the blister will help it heal and prevent bacteria from entering it. New skin will form under the blister and eventually cause it to pop. You can also take a sterilized pin and try to pop it yourself.
If the blister is filled with pus or blood, seeking treatment from a doctor is ideal. Antibiotics may need to be taken in order to completely eliminate the bacteria inside the blister. See a doctor to have an antibiotic prescribed.
The best way to treat blisters is to prevent them all together. Keeping your feet dry and making sure that your shoes fit properly are just two of the steps you can take to prevent blisters. Shoes that are too tight or shoes that are too loose and allow your feet to slide in them will cause blisters. Applying a bandage to an area where you think a blister is about to form is another way you can prevent them.
Cuboid syndrome mostly affects athletes, although it can affect non-athletes too. It is also known as cuboid subluxation or cuboid fault syndrome. This condition occurs when joints and ligaments near the cuboid bone of the foot are damaged, or when the cuboid bone itself is dislodged from its natural position. It is usually marked by pain on the outer side of the foot, which may be persistent or may come and go. Cuboid syndrome can be difficult to diagnose unless it becomes severe and more noticeable. Your doctor will likely ask questions about when the pain began and how long it has been present, and will put pressure on the cuboid bone to determine if that area is the origin of the pain.

Disagreements Amongst Podiatrists Regarding Cuboid Syndrome
It is very important that when you experience any kind of pain on the side of your foot, you should seek medical care right away. If a subluxed cuboid is caught early, your feet may respond well to the treatment, and you can get back into sports or other activities again as soon as the pain subsides.
Your feet endure a great amount of stress each day from constantly allowing us to move around. It is important to stretch your feet to help prevent them from becoming injured. Your toes may easily deform into unhealthful positions if they are not stretched.
One of the most common reasons for toe deformities are the shoes you may be wearing. Shoes that are too tight may fold and shift the toes out of place. Heeled shoes may also push your toes upward. Forcing your toes into an unnatural position which may cause the muscles to tighten and prevent them from reverting to normal length. Another common reason is improper use of foot muscles. Many people fail to use the muscles in their feet or toes when they walk. Lastly, the positioning of your feet while walking may also cause toe deformities. If you walk with your feet facing outward, your “push-off” phase is on the side of your big toe instead of the bottom of your foot. This may cause the big toe to eventually tighten into a new shifted position.
There are many reasons why stretching your toes may be helpful. One reason is that healthy spacing may aid in avoiding calluses and other injuries that are caused by rubbing. Stretching will also prevent you from developing toes that curl, hammertoes, or bunions.
A great way to stretch your toes is to place them in your hands and bend them all downward; this will help you stretch the top of your foot. Next, you should repeat this process but instead bend them upward enough to feel a nice stretch in the bottom of your foot. You should then try to pull each toe apart from the next and pull any toes that are bent upward until they are back downward.
If you are looking to practice stretching your entire foot, you can try a towel stretch. This is done by sitting on the floor with your legs in front of you. Take a towel and wrap it around your toes. Afterward, pull the towel toward you with your toes and hold this position for 15 to 30 seconds before releasing. Practice this stretch for three sets. Another stretch your feet are towel lifts. This is done by sitting in a chair and trying to pick a towel up from the ground with your toes. Try lifting the towel with your little toes for five sets before switching feet.
If you are an athlete, or exercise often, it is especially important for you to practice stretching your feet. Those who suffer from foot pain caused by poor footwear, plantar fasciitis, or long hours of standing at work may also benefit from foot exercises.
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.
Gout, typically found in diabetic patients, is an unusually painful form of arthritis caused by elevated levels of uric acid in the bloodstream. The condition typically strikes the big joint on the big toe. It has also been known to strike the knees, elbows, fingers, ankles and wrists—generally anywhere that has a functioning, moving joint.
The high level of uric acid in a person’s bloodstream creates the condition known as hyperuricema—the main cause of gout. Genetic predisposition occurs in nine out of ten sufferers. The children of parents who suffer gout will have a two in ten chance of developing the condition as well.
This form of arthritis, being particularly painful, is the leftover uric acid crystallizing in the blood stream. The crystallized uric acid then travels to the space between joints where they rub, causing friction when the patient moves. Symptoms include: pain, redness, swelling, and inflammation. Additional side effects may include fatigue and fever, although reports of these effects are very rare. Some patients have reported that pain may intensify when the temperature drops, such as when you sleep.
Most cases of gout are easily diagnosed by a podiatrist’s assessment of the various symptoms. Defined tests can also be performed. A blood test to detect elevated levels of uric acid is often used as well as an x-ray to diagnose visible and chronic gout.
Treatment for gout simply means eliminating symptoms. Non-steroid anti-inflammatory drugs or NSAIDs (Colchicine and other corticosteroid drugs, etc.) will quell the redness, the swelling, and the inflammation. However, managing your diet, lifestyle changes, and using preventative drugs are all helpful toward fully combating the most severe cases.
Those that lead an inactive lifestyle are at a higher risk for gout. Any amount of exercise decreases the probability of repeat encounters with the condition. Reducing your consumption of red meat, sea food, and fructose-sweetened drinks also reduces the likelihood of chronic gout as well.
Ingesting Vitamin C, coffee, and particular dairy products can help with maintaining a healthy lifestyle. There are new drugs out on the market that inhibit the body’s production of uric acid-producing enzymes. However, reducing or eliminating your overall levels of uric acid is the best remedy to ensuring you lead a gout-free life.
In most cases, foot surgery is often chosen as the last available option for conditions that have otherwise been unsuccessfully treated. Surgery may be necessary for several reasons, including the removal of foot deformities (e.g. bone spurs or bunions), arthritis problems, reconstruction due to injury, and congenital malformations (e.g. club foot or flat feet). Regardless of one’s age, foot surgery may be the only successful option for treatment for certain conditions.
The type of surgery one undergoes depends on the type of foot condition the patient has. For the removal of a bunion growth, a bunionectomy is necessary. If the bones in the feet need to be realigned or fused together, a surgical fusion of the foot is needed. For pain or nerve issues, a patient may require surgery in which the tissues surrounding the painful nerve are removed. Initially, less invasive treatments are generally attempted; surgery is often the last measure taken if other treatments are unsuccessful.
While in many cases surgery is often deemed as the final resort, choosing surgery comes with certain benefits. The associated pain experienced in relation to the particular condition is often relieved with surgery, allowing patients to quickly resume daily activities. The greatest benefit, however, is that surgery generally eliminates the problem immediately.
Podiatry history has shown that foot treatments continue to evolve over time. In the field of foot surgery, endoscopic surgery is just one of the many advanced forms of surgery. As technology vastly improves so too will the various techniques in foot surgery, which already require smaller and smaller incisions with the use of better and more efficient tools. Thanks to such innovations, surgery is no longer as invasive as it was in the past, allowing for faster and easier recoveries.
Rheumatoid Arthritis is a chronic progressive disease that attacks several joints throughout the body. It is an autoimmune disease in which the body’s immune system mistakenly attacks the joints. As a result, the tissue inside the joints, called synovium, starts to thicken and causes pain around the joints. The synovium is responsible for creating a fluid that lubricates the joints to help them move. Approximately 1.5 million people in the United States have Rheumatoid Arthritis. Women are almost three times as likely to have RA compared to men, and it’s disease usually begins between the ages of 30 and 60. People who have a genetic history of RA are more likely to develop the disease.
Symptoms of RA may include the following sensations in the joints: pain, tenderness, swelling, redness, warmth, stiffness, and loss of range. Swollen joints are a very common symptom for those with the disease. At times, it may be minimal, but it may also be very apparent. Another typical symptom is joint stiffness. Doctors will often use the direction of morning stiffness to measure the severity of a patient’s joint inflammation. Other RA symptoms include limping, anemia, fever, and fatigue.
To diagnose RA, your podiatrist will typically request x-rays to see how much damage there is in the joints. Blood tests may also be performed to show if there are any signs of anemia, or antibodies such as the rheumatoid factor. If you have previously been diagnosed with RA, you should know the disease may spread to your feet and ankles.
There are many non-surgical options that can be used to treat this ailment. Some of these options include physical therapy, foot massages, orthotics, bracing, supportive shoes, and steroid injections. Physical therapy is useful because it will help stretch and strengthen the joints in both the foot and ankle to improve joint function. Massages can help improve blood circulation which will be good for the feet. Choosing proper footwear will allow you to walk with comfortability if you are a sufferer from RA. Lastly, bracing will help stabilize the foot joints, limit deformities and decrease pain.
In severe cases, surgery may be a treatment option that should be considered. For those who cannot walk without experiencing pain and those whose deformities can not be managed with braces, surgery should be considered. Your podiatrist will recommend surgery if he or she believes it will improve your foot biomechanics.
