[Larien]

On Saturday I woke up with severe, full body hives. They lasted until Monday and my doctor said the cause was internal since creams don't work, and she gave me a medrol dose pack and Allegra.

I'm on the second to the last day of the pack, and I still have the hives. They seem to fad during the day after my Allegra dose but they become so severe at night that I can't sleep.

It seems like they start brewing after my nightime medications: Toprol XL and Tramadol ER. I have been on these medications for about a year with no other problems, and I know it's not a food allergy because I haven't eaten out in months and I'm a picky eater with limited range already.

Also, a couple weeks ago I had an injection of something for bursitis in my right hip, I'm not sure what it was exactly.

Is it possible that one of those medicines is causing a delayed reaction in me all of the sudden?
