My daughter suffered from this for TWO YEARS. Her uticaria started after a round of antibiotics, but we never did find for certain what caused it. I quickly became a fan of alternative medicine as well, but after TWO YEARS and FOUR different clinics, we gave in and put her on a steriod for 3 days. It completely stopped for a few weeks and we're down to one break out every couple of months. We never did find a natural solution, and you wouldn't believe what we tried. Filters on the shower heads, only purified drinking/cooking water, STRICT diet eliminating certain things for periods of time, allergy testing, detoxing... Oh, it went on and on... I feel for you as the anxiety my little girl experienced during the breakouts was just gut wrenching. I would have to hold her, all wrapped in a line dried towel, rubbing her back without scratching until the benadryl kicked in. I would try seeing an allergist. Have them do blood work, just to make sure your counts are right. Wierdly enough, whenever my daughter had bad breakouts, her counts were off. Never did figure that out either. The good news is that she's much better now... I hope you're all better soon too!!
