I get hives on my body everyday, at midnight as well with symptoms like discomfort in the upper stomach, loose motions or sometimes constipation, sometimes also accompanied by heartburn like feeling but in the whole body and a lump in throat when the hives are really bad. The hives go when I take Montek LC and so do most of the stomach problems(most not all like loose motions still remain). I am also getting frequent mild UTI(twice-thrice in 6 months) and I have a feeling all these are related. Could this be food intolerances, IBS, histamine intolerances? What should I do to get relief at home as I can't go to a doctor for a couple of weeks. And what doctor do I go to? An Allergist, GP?
