It is suspected that I have acid reflux disease. I was prescribed 20mg omerpazole, twice per day. A week later, I developed an extreme sore throat, swollen tongue which has a numb sensation, fire red gums, red throat with blisters on the upper palate. This lasted 2 weeks and during this time, I was prescribed amoxicillin with the thought that I had a bacterial infection. The symptoms began to subside, I resumed the omerprazole and the swollen tongue, red gums came back with a vengeance. Does this sound like an allergic reaction? Could I be experiencing chemical burn from acid reflux. I am desperate! Could this be caused by taking the omerprazole with food instead of an empty stomach?
