Psoriasis
Psoriasis is the sudden buildup of scaly and rough skin that results in skin rashes. Psoriasis occurs when there is a rapid increase in the life cycle of skin cells. The extra skin cells form silvery scales, and thick patches which cause severe pain and irritation. The skin rashes in psoriasis tend to flare up periodically and might subside for a time. Topical medications might help in reducing the symptoms of skin lesions. There can be disabling and extensive areas of skin rashes for some people.
