A member asked:
Hives urticaria x 3 weeks. antihistamines and prednisone are moderately effective only with consistent use. would a skin biopsy help determine cause?
A doctor has provided 1 answer
No: A skin biopsy can help prove that these are hives, but usually cannot help to identify a trigger (unless you have underlying blood vessel disease called vasculitis). Prednisone should be avoided if possible because the hives can come back stronger when it is stopped. There are many potential triggers to discuss with a physician and many effective treatment options. Recommend Health Tap consult.
