My 12 year old daughter was just diagnosed today with this. I read the other posts relating thyroid problems with autoimmune urticaria. Since I have hypothyroidism, I'm guessing that she should be tested for this at her regular doctor's office? Right now all I can afford is the double dose of Zyrtec, but with everything else she's allergic to (7 types of trees, 3 molds, ragweed, cat, feathers,dust mites & roaches of course) the allergy shots would be better for her, right? Does anyone know how to get reduced rates on allergy shots since her dad's insurance is crappy, pardon the expression. Also, it looks like she needs to take the double dose of Zyrtec at night; is this right? Appreciate any help.
