Psoriasis is a skin condition that can appear on the legs and feet, as well as other body parts. It is a chronic disease of the immune system wherein new skin cells surface too rapidly, causing inflamed, flaky, thick patches of skin buildup. It is characterized by the appearance of thickened skin patches with white, red, and grayish-silver pigmentation. The areas can be small and localized or larger and more widespread. Psoriasis can cause itching and pain as it progresses. On the feet and toenails, it may be mistakenly assumed to be athlete’s foot and other fungal infections.
Psoriasis is an autoimmune disease and tends to run in families. It tends to be more severe in people with weakened immune systems, including those with AIDS and those undergoing treatment for cancer. Stress also seems to make the skin condition worse.
Psoriasis can also affect the joints in the feet and legs, causing arthritis. This condition can be hard to treat, but sufferers may gain relief from keeping the skin well moisturized, anti-inflammatory medications, and prescription medications prescribed by a doctor.
You can’t prevent the development of psoriasis, but you can avoid things that make it worse. Stress management techniques may help some people with the condition. Alcohol, dry air, and too much or too little sunlight seems to trigger it for some people, so controlling your exposure to things that irritate it may help.
