How long Do Hives Normally Last?

How long will my hives last?

• Today is Wednesday: On Sunday afternoon, I got a few hives that progressively got worse as the day went on. By Monday morning they were all over me. I went to the doctor that afternoon, and he told me that I had either ate, drank, or breathed in an allergin. At the time, I couldn't think of anything new I ate or drank. He perscribed me prednisone, which I took as soon as I got home. By the next morning(Tuesday), my hives were almost completely gone. By Tuesday evening, the hives had returned in almost full force. Only now they were VERY itchy. I thought really hard about what could be causing it. The only thing I could come up with was Galliker's Low Fat Milk. I had drank it for the first time ever Sunday morning before I got the hives, and then I drank some Monday and Tuesday morning as well. I had Gallikers Whole Milk, and other brands of Low Fat Milk in the past without problem. So, I guess I have a few questions: 1. Could I be allergic to one brand of Low Fat milk and not another? 2. If it is the milk that's causing the problem, how long will these hives last. (I stopped drinking the milk about 36 hours ago.) 3. How come I still have hives even though I've been taking prednisone, and the first time I took the pills, the hives went away? Please help! They are incredibly aggravating. I can't even sleep because they itch so terribly. And, if it's not the milk, it HAS to be airborne. I can't figure this out and it's driving me nuts.

• Answer:

  till they're gone. drink more water, take your meds exactly as prescribed, keep a food diary, and see your allergist.
