Results from an ESR (sed rate) test may be high. Skin biopsy shows inflammation of the blood vessels.
The goal of treatment is to reduce inflammation.
Aspirin or corticosteroids may be prescribed to reduce inflammation of the blood vessels. (DO NOT give aspirin to children except as advised by the health care provider.)
If possible, your doctor may tell you to stop taking the medicine that caused this condition. Do not stop taking any medicine without first talking to your doctor.
Allergic vasculitis usually goes away over time.
