Urticaria

Help! I've developed urticaria!! Don't know what's the reason because I'm not allergic to anything, but it certainly doesn't look pretty! By the way, urticaria or better known as hives is a rash on the skin. Weird thing is, I don't feel itchy at all. I have some patches on my body, but lots on my leg. It's horrible! I'm taking some antihistamines, hopefully it will go away in a couple of days! ... sorry, no picture on this.. Don't want to scare anyone and I certainly don't want to look at it, nor have any remembrance on that!
