Urticaria (Hives)-help needed urgently?

Sounds like you need to go see a good dermatologist. Did they load you up on any prednisone? You might trying taking some H2 blockers ie: Zantac, Prilosec etc. You might also try some OTC benadryl (diphenhydramine). I find it kind of funny that you only have them in the evenings and into the late morning. Stress can also play a role in giving you uticaria. Are you going home to something that stresses you out? Anyways you might go to a dermatologist and have them test you for allergens just to be on the safe side. Good luck.
