Hi! My Name Is Brad M And I Have Had

Hi! My name is brad m and I have had stomach ulcers over the last7 years and I have a stomach Dr. My ulcers have continued to get worse and are causing severe pain that is almost unbearable I am taking nexium but they never have helped!I have had so many endoscopies I lost count and when I go to my gi Dr he always does endoscopies and biopsy with no change except ulcer is growing. I just don't no what to do now the pain is worrying me as its so severe what should I do? My weight has dropped 15pounds in last 3week's I can't eat because it makes the pain a lot worse I am worried that it might b cancerous. When I do eat I take two or three bites and it feels like I ait 10hamburgers I just want it better but tired if getting the same thing over and over with no good outcome should I find a new gi doc or something? Any info u can give me would b great I just want to b able to live without pain and have energy again.thank you for your time!
