I'm saddened to see that so many folks can't see a doctor because of lack of insurance.
I have read of people getting ulcers at your age. I think the gold standard for checking out problems like these is an endoscopy and a test for H Pylori bacteria. No one wants to go through it, but I suspect things will only get worse if you don't get it checked out by a professional.
I have tried Zantac, been taking prilosec for a month and half, have tried maalox and a gas pill. No luck
Have you tried an antacid or something like Pepto-Bismol or Zantac - which I think reduces the amount of acid secreted by the stomach in order to reduce ulcer and heartburn pain or to assist in healing of ulcers - I'm pretty sure it is used to treat stomach and duodenal (intestinal) ulcers, and gastroesophageal reflux disease (GERD). That might point you in the right direction. Sounds like you should still see your GP though.
