[|Human|] My shin started itching randomly one morning, and has been annoyingly itchy ever since 2 weeks ago. There is a colorless rash that looks like goosebumps, and when itched the rash becomes slightly numb and raised when itched. It spread to my other leg, though not as bad, and I fear that it could be spreading up farther past the knee. Diagnosis? Treatment? Either is appreciated. (I had a nasty case of poison oak about half a year ago, where the rash was all over my body, including the legs. Could this be the cause?)

Cause may be irritation, allergy,heat, solar,cold, psychological,internal cause, Chat Doctor. . You should undergo varieties of blood tests. If there is any cause is found., cause should be treated. If no cause is found, it is called idiopathic urticaria. You take antihistamines like fexofenadine, deloratidine, levocetirizine....etc Short course of steroid may be taken. Avoid soap bath.
