Gentle hugs to you. I have been there, unfortunately, and it does suck!
Have you tried going to urticaria groups? There's one that I've used (and recommended) many times.
http://www.urticaria.thunderworks.com
A few people, like Jackie, are extremely helpful and knowledgeable about the symptoms and causes, tests, as well as helpful treatments. Many, many members are very supportive, as they've suffered too. It's a very helpful site.
Very best wishes to you Phrick!!
