Welcome to Connect, @willow5. Chronic itching is so miserable! I experienced that issue for several months while undergoing treatments for an illness I had. It was almost unbearable and I swear, worse than pain! I’m so sorry you’re experiencing this condition of chronic hives. While you’re waiting for other members with urticaria to join the conversation with their suggestions for relief from itching, I did find quite a few discussions in the forum that might be helpful.

I also found a couple of articles that discuss Chronic Hives and the possible involvement of eosinophils. Eosinophils are a type of white blood cell that fight infections and allergic reactions.

Have you had blood work to test for thyroid issues, autoimmune diseases, or allergies?
