I have had abdominal pain for 1 month now. I have had ct scans that were clean, ultrasound that was clean, hidascan that was clean, and blood and urine where great. The doctor treated me as having inflammation or an ulcer. The pain is still there. Its all over, upper abdomen, lower abdomen, and I just started feeling nausea. I tried throwing up but just dry heaved. After that I spit up mucus and blood. It wasn t large amounts of blood but enough to make me wonder if I should go to the emergency room. Any ideas?
