Diseases of the foot

Diseases of the foot generally are not limited, that is they are related to or manifest elsewhere in the body. However, the foot is often the first place some of these diseases or a sign or symptom of others appear. This is because of the foot's distance from the central circulation, the heart and its constant exposure to pressures from the ground and the weight of the body. Diseases of the foot generally are not limited, that is they are related to or manifest elsewhere in the body. However, the foot is often the first place some of these diseases or a sign or symptom of others appear. This is because of the foot's distance from the central circulation, the heart and its constant exposure to pressures from the ground and the weight of the body. The foot may look simple but is a complex structure with 26 bones, 33 joints, numerous muscles, nerves and different ligament types. Any part of the foot can be affected. Some foot disorders may present with just a mild ache, but other foot disorders can be very serious and limit ability to walk or bear weight. Most minor cases of foot pain respond to home care treatments except when severe pain is present as it is a disabling condition and usually needs some type of medical attention. If foot pain is not treated in time, it can lead to long term disability and continuing damage to the foot. The most common cause of foot pain is wearing ill fitting shoes. Women often wear tight shoes that are narrow and constrictive, and thus are most prone to foot problems. Tight shoes often cause overcrowding of toes and result in a variety of structural defects. The next most common cause of foot disease is overuse or traumatic injuries. Besides a physical examination, an x-ray MRI or an ultrasound study may be obtained to assess the soft tissues and blood vessels. Standardized questionnaires and scoring systems, like the American Orthopaedic Foot & Ankle Society (AOFAS) foot and ankle questionnaires, can help elicit the history and physical exam necessary to make and accurate diagnosis of foot and ankle conditions. Often there is a distinction made between conditions of the dorsal skin and plantar skin. Common examples include callus thickened skin, fungal infections of the skin (athlete's foot) or nails (onychomycosis), viral infection of verrucae, and ingrowing toenails that may cause bacterial nail infections (paronychia). Corns and calluses are chunky tough layers of skin that develop on the foot to protect underlying skin from pressure and friction. Corns and calluses are very common and do not look pleasant. Corns and calluses generally need treatment only if they cause problems. For most people, the best treatment of corns and calluses is to eliminate the source of friction or pressure. Ingrown toe nail is a disorder where the nail starts to grow into the soft fleshy area of the toe. It causes intense redness, pain and swelling. Ingrown toe nails often affect the big toe. The best treatment for ingrown toe nails is to get the nail partially or completely removed. Arthritic foot conditions often present differently from arthritis other areas of the body. Achilles tendinitis results from stress on calf muscles and Achilles tendon. This strong tendon often gets inflamed while playing sports like basketball. The tendon gets irritated and does cause moderate pain . When treated promptly, the tendinitis is relieved. Sometimes, the Achilles tendon can rupture if it is overstretched. When the Achilles tendon ruptures, one may feel a sudden pop followed by sharp pain. Rupture of the Achilles tendon makes it impossible to walk. Bunion is an abnormal bony mass that forms on the big toe and points outwards. This deformity is unsightly and painful. When the big toe enlarges at the base, it can force the other toes to crowd against each other. Over time, the big toe pushes outwards and alters the normal outline of the foot. Bunions occur for many reasons but the most common is not wearing proper shoes, arthritis and different inherited structural defects.
