I started getting severe stomach acid about a year and a half ago. I started taking prevacid for it, but nothing seemed to help. Then I started breaking out in hives. I saw an allergist who did a scratch test on me, and it came back positive for some trees and things. I started taking clarinex, but it didnt help. I was switched around from a few different allergy meds. Now Im on zyrtec. At one point, the allergist had me on singulair, zyrtec, clarinex, and allergra, and still, no relief. Then I started getting a severley itchy mouth. Now its the dead of winter, and Im still having the hives, itchy mouth, and severe stomach acid. So Im going to assume its not outdoor allergies! Lol. Arrgghhh. Its so frustrating, and so uncomfortable!
