Q：
What causes chronic idiopathic urticaria?

Answer 1

Chronic idiopathic urticaria is a type of urticaria. For a small number of people, hives or urticaria come back again and again with no known cause.

The exact causes of chronic idiopathic urticaria are still unknown, but several things can lead to flare-ups, which include:

• Tight clothing
• Exercise
• Heat
• Cold
• Nonsteroidal anti-inflammatory drugs (NSAIDS) like aspirin and ibuprofen
• Alcoholic drinks

Comments

Could you please show us a picture of the rash? Without looking at the rash, it is really hard to give a suggestion. Otherwise, go to see a dermatologist.
