You clearly are very stressed out in life now so things are not helping.
The condition is urticaria
, that does get difficult to manage with allegra/zyrtec if you are stressed as well. If these hives are definitely after eatinh wheat products, then a blood test
while on normal diet for IgA-TTG can help to decide if you have coeliac
disease. If the test is positive, then yes, gluten-free diet
is the treatment
Otherwise, you have to persevere with the antihistamines for 4-6 weeks and eventually they will stop. You can ask your doctor for a 5 days course of prednislone/deflazacort
if you are in real trouble.
