I have stomach ulcers and I want to know more about it. What are the causes and symptoms?

No single cause. Infection with a type of bacteria called helicobacter pylori (h. Pylori) use of painkillers called nonsteroidal anti-inflammatory drugs (nsaids), such as aspirin, Naproxen Ibuprofen and many others available by prescription. Rarely excess acid production from gastrinomas, tumors of the acid producing cells of the stomach.
