Psoriasis is a common skin condition that causes red, itchy, and scaly patches on the skin. It can affect any part of the body, but it most commonly occurs on the elbows, knees, scalp, and trunk. Psoriasis is not contagious, but it can be uncomfortable and embarrassing. There is no cure for psoriasis, but there are a number of treatments that can help to control the symptoms.
The word psoriasis is derived from the Greek words “psora” meaning “itch” and “iasis” meaning “condition”. The condition was first described by Hippocrates in the 5th century BC. Psoriasis is a chronic condition, which means that it can last for a long time. However, it is not usually life-threatening. The symptoms of psoriasis can vary from mild to severe. In some cases, the symptoms may only be present for a few weeks or months. In other cases, the symptoms may be present for many years.
