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.
Plantar warts are described as small growths that appear on the heels or other areas of the feet that bear a large amount of weight. The pressure in these areas causes plantar warts to hide behind thick layers of skin called calluses. In most cases, plantar warts are not a serious health issue, and they usually go away without treatment. However, it is still important be mindful of them.
Plantar warts are caused by infections with human papillomavirus (HPV) in the outer layer of skin on the soles of the feet. The plantar warts then develop when the virus enters the body through weak spots at the bottom of the feet, such as tiny cuts and breaks. Plantar warts are not guaranteed for all who encounter the virus. Everyone responds differently to the affects of HPV.
Plantar warts are most common in the following groups: children and teenagers, people with weakened immune systems, people with history of plantar warts, and people who walk barefoot. Exposure to HPV is common in environments such as locker rooms or pool areas.
One of early signs to look out for is a callus, since many plantar warts hide behind them. You can also locate these warts by looking for small, fleshy, rough, grainy growths near the base of the toes and the heel. Early signs of plantar warts are shown by black pinpoints, which are small, clotted blood vessels. Lesions that interrupt normal lines and ridges in the skin of your foot may also be a sign of plantar warts. Any feeling of pain while walking or standing can also be a symptom of plantar warts.
Although most cases are not serious, some conditions may require a visit to your podiatrist. If you are uncertain that your lesion is a wart, if you have diabetes, or if you are experiencing bleeding, you may need to see a seek professional treatment. Your doctor may offer treatments such as prescribing stronger peeling medicine or using cryotherapy by applying liquid nitrogen to the wart. More serious cases may require minor surgery or laser treatment.
There are simple solutions available to help prevent plantar warts. One common task is to avoid walking barefoot in swimming pool areas and locker rooms, as this is where HPV is commonly present. Keeping your feet clean and dry, while changing shoes and socks daily can also help prevent future plantar warts. If you know someone who has plantar warts, it is important to avoid direct contact with their warts. You should also refrain from picking or scratching your wart if you happen to develop one.
Sesamoiditis is a condition that affects the joint that is just behind the big toe in the area known as the ball of the foot. It is most common in younger people and people who have just begun an exercise program. Since the sesamoid bones are like a pulley controlling the big toe, they can rub against each other and cause a gradual onset of pain. Pain may also be caused by the inflammation of tendons surrounding the bones. If ignored, sesamoiditis can lead to other, more serious problems such as severe irritation and fractures of the bones.
The cause of sesamoiditis is sudden increase in activity. The ball of your foot acts as a springboard to help you lift off when you are jogging or running. Sudden increase in the use of these bones or the tendon that controls them can cause irritation. The tendon then begins to develop inflammation and the joint begins to swell. People with smaller, bonier feet or those with a high arch are typically more susceptible to this condition.
Sesamoiditis is fairly simple to diagnose since the symptoms have a gradual onset rather than a sudden impact. The symptoms begin with slight irritation around the joint shortly after the increase in activity. The discomfort eventually turns to pain with light swelling and possibly redness. Although redness or bruising are rare, this may be a symptom. After each session of exercising, the aggravated joint becomes more irritated and increases into a very intense throbbing.
Treatment for sesamoiditis can vary depending on the severity of the situation. However, treatment is almost always approached in a noninvasive way. For a case that is just beginning the doctor may recommend a very strict rest period that will limit the activity allowed on the joint. If you must be active, a recommendation for as modified shoe or insole, along with bandaging and immobilizing the big toe will be made to ensure that pressure is not placed on the joint. For severe cases, it is typically recommended that the joint and the big toe be completely immobilized to allow adequate time to heal. Ice and an over the counter anti-inflammatory may can help with the pain and discomfort while you are at rest.
When you return to your regular exercise activities, it is recommended that you use an insole that will allow even distribution of impact to your entire foot, rather than just the balls of your foot. This will prevent further aggravation of the injury.
A bunion is a bump that forms at the base of the big toe. Bunions form when the big toe pushes against the next toe, which forces the big toe joint to get bigger and stick out. As a result, the skin over the bunion may start to appear red and it may feel sore.
There are risk factors that can increase your chances of developing bunions. People who wear high heels or ill-fitting shoes are more likely to develop them, in addition to those who have a genetic history of bunions or have rheumatoid arthritis.
The most obvious way to tell if you have a bunion is to look for the big toe pushing up against the toe next to it. Bunions produce a large protrusion at the base of the big toe and may or may not cause pain. Other symptoms are redness, swelling, and restricted movement of the big toe if you have arthritis.
Nonsurgical methods are frequently used to treat bunions that aren’t severe. Some methods of nonsurgical treatment are orthotics, icing and resting the foot, taping the foot, and pain medication. Surgery is usually only required in extreme cases. However, if surgery is needed, some procedures may involve removing the swollen tissue from around the big toe joint, straightening the big toe by removing part of the bone, or joining the bones of your affected joint permanently.
Your podiatrist will diagnose your bunion by doing a thorough examination of your foot. He or she may also conduct an x-ray to determine the cause of the bunion and its severity.
One out of ten broken bones is reported to be in the feet. When an object crushes, bends, or stretches the bone beyond acceptable ranges, bones break. A break in the foot is either a fracture or a straight break.
The location of any break can tell you how the break happened. Toes, for instance, break typically as a result of something being kicked hard and with great force. Heel breaks almost always are a result of an improper landing from a tall height. Twists or sprains are the other two frequent occurrences. As with all usual breaks, they result from unexpected accident or sudden injury. As with stress fractures, breaks form as a process over time from repeated stress on already present cracks. Runners, dancers, and gymnasts are the usual athletes who receive this type of break. Stress fractures result from incredible pressure on the feet. It is no surprise these athletes bear the majority of reported fractures.
Pain, swelling, bruising, and redness are all indicative of the typical symptoms from a broken foot. Severe pain—to the point of not being able to walk—usually depends on the location of the break in the foot. Toes are on the lower scale of pain threshold, but heels are high, as are a few other particular bones. As the severity of the broken foot increases, symptoms like blueness, numbness, misshaping of the foot, cuts, or deformities will become apparent. These symptoms indicate the need to see a medical professional with access to an x-ray facility.
Prior to seeing a specialist, precautions should be taken to reduce pain and swelling. Elevate and stabilize the foot, and refrain from moving it. Immobilization of the foot is the next priority, so creating a homemade splint is acceptable. Keep in mind that while creating a splint, any increase of pain or cutting off blood circulation means that the splint should be removed immediately. Use ice to decrease swelling and relieve pain symptoms.
When dealing with a medical center, the patient should note that the treatment can vary. The treatment will depend on the severity of the fracture and the cause of the break. Crutches, splits, or casts are common treatments while surgery has been known to be used in more severe cases in order to repair the break in the bones.
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 small pockets of fluid that occur on the top layers of the skin for several reasons. Friction, burns, and diseases are all known causes of blisters. Smaller blisters are known as vesicles, while larger blisters are referred to as bulla. The fluid inside the bubble can be blood, pus, or serum; which is a clear liquid that protects the skin. In most cases, blisters are not a major health issue, but they can be an indicator of a more serious condition.
Causes of blisters vary. Blisters are commonly caused by wearing poorly fitted shoes that rub against the foot. However, there are many other causes besides from friction; including burns, sunburn, insect bites, frostbite, poison ivy/oak, chemical exposure, impetigo, eczema, viral infections, and more.
Most blisters heal by themselves and do not require immediate medical care. If you have a blister, do not pop it since this may cause infection; it is advised to put a bandage over the blister to protect it. If the blister is large, causes pain, or if you have a fever, it is recommended that you see a doctor who can provide proper care. Blisters are easy to diagnose, and if considered prudent by the doctor, can easily be drained of fluid with a sterile needle as well.
To prevent blisters on the feet, wear shoes that fit properly and don’t cause rubbing. Socks can help prevent friction and it is recommended that you wear them if you are wearing shoes. Hand blisters can be avoided by wearing gloves during activities that cause friction against the hand. If you have a blister that pops, do not remove the dead skin, wash the area, apply antibiotic ointment, and cover with a bandage. It is okay in most cases to not seek immediate medical care for a blister if it was just caused by friction. However, if the blister causes pain or does not go away, it is suggested that you see a doctor for a diagnosis.
