Other areas that may be affected include the hindfoot (back of the foot) with heel pain from Plantar Fasciitis (inflammation of a ligament extending from the heel to the toes), tendonitis of the Achilles tendon or even bursitis (inflammation of a fluid filled sack at the back of the ankle). RA, as an inflammatory disease, may also include neuropathy (loss of nerve functioning including numbness or muscle weakness), vasculitis (inflammation of the blood vessels), ulcerations (wounds), necrosis of the toes or even gangrene. Even ordinary problems can quickly get worse and lead to serious complications.
If you have diabetes or another condition that causes poor circulation to your feet, you're at greater risk of complications. Corns are smaller than calluses and have a hard center surrounded by inflamed skin. Corns usually develop on parts of your feet that don't bear weight, such as the tops and sides of your toes. Corns can be painful when pushed or may cause a dull ache. Calluses usually develop on the soles of the feet, especially under the heels or balls, on the palms, or on the knees. Calluses are rarely painful and vary in size and shape. They can be more than an inch in diameter, making them larger than corns. When shoes are too tight or have very high heels, they compress areas of your foot. Repeat two to three times; switch feet.
A clavus is a thickening of the skin due to intermittent pressure and frictional forces. The word clavus has many synonyms and innumerable vernacular terms, some of which are listed in the Table below; these terms describe the related activities that have induced clavus formation. The shape of the hands and feet are important in clavus formation. Specifically, the bony prominences of the metacarpophalangeal and metatarsophalangeal joints often are shaped in such a way as to induce overlying skin friction. Toe deformity, including contractures and claw, hammer, and mallet-shaped toes, may contribute to pathogenesis. First, you had better prepare for a basin of warm water to soak the feet every winter night.
A callus is actually a bone problem and a foot mechanics problem, not a skin problem. A foot deformity will cause excess pressure to that area from the shoe or the ground. The body's natural defense mechanism will kick in and start building up the top layer of skin in response to the excess pressure. This is a protective response from the body in an attempt to prevent the pressure from wearing down the skin layers and resulting in an open sore. The problem is that as long as there is pressure, the body will continue to build up the skin. In runners, the most common places for callus buildup are at the inside of the heel, the area around the big toe and the ball of the foot. Calluses can appear on top of the toes or in between the toes. In these cases, the callus tissue is called a corn. The calluses can be thickened, dry, scaly, yellow, red, tender and even flakey. Once the problem is identified, the first step is to treat the cause. Metatarsal pain is a common foot problem.
