I have adbominal pain, gas, burps, no appetite. After gas is released, the pain disappears. Taken clarythrominin, amoxilin, and omeprazol...?

Not sure. Have you had a gastric emptying study? If you have a slow to empty stomach, this can often have these symptoms. Patients with severe gerd often swallow a lot of air. This distension will feel better when released. Otherwise, it may be irritable bowel syndrome. See a GI doctor.
