Henoch Schonlein purpura

Henoch-Schonlein purpura is characterized by skin petechia, mostly in lower limb around joints and hips. The petechia generally subsides in a few days, but can be recurrent. Symptoms include abdominal pain, joint pain, proteinuria, and blood in urine. It is more common in children. Doctors should try to identify the cause of an allergy and avoid it. Antihistamines can be used for treatment.
