I was diagnoised with Duodenal Ulcer/Duodenitis about a month ago. I was in the hospital for a week. The pain and the symptoms are all returning and I do not know what to do. I am taking carafate and protonixs. They did a biopsy to check for h.pylori but it came back negative. I have read that you can have a false negative and almost 99% of the time if you have Duodenal Ulcers you have h.pylori. Could I have h.pylori. When I had the endoscopy my stomach was raw, inflammed and red. I also had white spots all over the Duodenal. As of this week I have a new symptoms my chest burns like it is on fire and nothing helps it. I also have the sensation of a lump in my throat. I do not know what to do. I hate to go back to the ER but I do not know what else to do.

Summarized question: What causes recurring duodenal ulcer?
