Treating Plaque Psoriasis
Psoriasis is an autoimmune disease. The most common type of psoriasis is plaque psoriasis, and it is characterized by red, raised, and wrinkly patches on the skin. The patches are typically covered in a silver-white buildup of dead skin cells and can be itchy or painful. If left untreated, the skin can crack and bleed. They usually occur on the scalp, knees, elbows, and/or lower back.
If you start developing an itchy rash that does not go away with over-the-counter medication, contact your doctor. The doctor will then look for any red, raised scales with well-defined edges, as well as examine how the rash responds to other medications before diagnosing you.
