I am in so much pain and it is suspected that i have gerd or an ulcer. medication wears off and i'm in a lot of pain. what to do?

Try sipping: small quantities of milk (If you are lactose intolerant include "lactaid" tablets.) Also an oral antacid (for example Maalox, Gelusil etc) may help ! You failed to mention what medication you were started on and what is planned for tests to determine exact diagnosis! Over the counter H-2 blockers (eg Pepcid (famotidine) , Zantac< may also help! Hope this is helpful! Dr Z
