GI bleeding

Hi, I have been having recurrent GI bleeding episodes since 2001. The doctors have rules out H.Pylori, NSAIDS. Everytime the ulcer is at upper duodenum. In the first episode although H.Pylori was ruled out they gave antibiotics and Nexium for couple of weeks. When it happened again after few years they put me on Nexium permanently and then even on Nexium I started getting pains for the past 8-9months and they did a series of tests again and couldn't find anything. Then we went to another GI specialist and he stopped my Nexium and then I had GI bleeding again. It is very rare to have a recurrent bleeding episode without any apparent cause except excessive acid. Do you have any explanation and remedy for this condition?

Hi,
Was biopsy done?
Is it a single ulcer or multiple ulcers?
Do you have any other symptoms?
