So sorry you have been feeling ill. Perhaps it is something in the air, where you live, triggering your symptoms or something you like to eat… which could be anything. Could be a perservative in some medicine that you take. It really could be any number of things triggering your mast cells to degranulate. I did the elimination diet, gluten and stawberries are big triggers for me. Alcohol too. Do you take any benedryl? I know they say save it for when you are really sick maybe you can take them more regularly until you get the mast cells in check? Just a thought.
