One after another. Last week my dream job offer came, then happened the urticaria. It was itching & burning like hell! I had a dentist appointment that I missed as of the severe and constant itching all over. Went to a doctor about it and he said: “We don’t know why urticaria happens. (Doctors, eh?) Just take these antihistamines. There is no cure (I know hun) but you can manage the symptoms.” Another auto-immune! Well, I took those antihistamines and they made me sleep all day and forgot about the dental problem.
