Overview
Psoriasis is a disorder that affects both the skin and the joints, causing a characteristic rash and sometimes arthritis-like joint pain. The rash is usually red and raised, and the skin has a tendency to turn silvery and flaky on top of the red raised areas. Psoriasis can occur on any part of the body, including the scalp and nails. Approximately half of people who have the rash of psoriasis have fingernail changes, and a quarter have joint difficulties. Psoriasis tends to run in families (be hereditary) and is related to problems with the immune system. Psoriasis flares are triggered by many things, some of which are poorly understood; some scientists believe that viruses, injury to the skin (trauma), Streptococcus infection, stress, smoking, and alcohol can all trigger flares. There are no certain cures for psoriasis, but there are treatments that your doctor can prescribe that may help you manage the condition.
