Hi I have persistent nausea, which is sometimes made worse after eating. There is also sometimes pain, also in the stomach region, though that isn t as consistent. There s also more belching than usual. I ve had this for 2 mos now. I was tested for h. pylori and parasites, and had a CBC done. Everything came back as normal. I was diagnosed w/an ulcer before, so was surprised about the negative test. I have no other symptoms. Any idea what this might be?
