    Psoriasis is a noncontagious skin condition that produces red, dry patches of thickened skin. It is believed that dry skin flakes due to the rapid proliferation of skin cells triggered by the presence of abnormal blood cells. Psoriasis commonly affects the skin of the elbows, knees and scalp, but does not form blisters or itchy. And yours seems to come and go. The deshidrosis also cause dryness, with small blisters and can sting, but is usually limited to a zone. Many of the symptoms mentioned also occur with dermatitis herpetiformis, in which very small bubbles are produced, but the symptoms are different from those described. You need to consult a dermatologist to find out what happens. Injuries that does not seem to have any relationship with the fibriomyalgia or with osteoarthritis.
