on wednesday night I suddeenly had itchy,prickly, burning sensation in parts of my body. I then got all red for a few minutes and then it all passed. The following morning I went to the dermatologist. The Dr. said it was hives( I started erupting while in his office.) The Dr. said no idea as to how hives come or when they will leave.Anyone out there has hives. Input please. From wednesday to today monday Ihave had episodes almost everyday.Thanks for any input.
