Psoriasis is a skin disease that causes red, itchy scaly patches over the body, scalp or palms and soles. It is a common, long-term (chronic) disease. It tends to go through cycles, flaring for a few weeks or months especially during winters or in cold climate, then subsiding for a while or going into remission.
Though Psoriasis is a distressing chronic condition, it can be effectively controlled with the right medications and stress management. Additional benefit can also be achieved with the use of phototherapy.
