I have developed a rash/hives on my legs about a little over a week ago. They are small red dots and look like insect bites. Since then, they've appeared on my buttocks, a few on my stomach, and back and left side under the armpit just left of my left breast. Two days ago a new cluster of hives/rash appeared on my lower abdomen just above my lower region hairline and inside my right leg. I've never had a rash before. My husband does not appear to have anything. They are not painful, just VERY itchy and annoying. I checked the bed for beg bugs and I can't find anything. I'm not sure what this is. I don't have any known allergies either. I am 30, female and asian. Please help!!
