For the past three years, I've had moderate to severe abdominal pain only at night. It happens every night. Never in the day. I've been to the Dr's i did my Gastroscopy , Colonoscopy, CT scan, Blood tests, Ultra sounds and all. ALl comes with the good results . No issues at all. (Gastroscropy was bit of red but nothing major or ulcer ). I also did helicobector tests as well. ALl good with it . Tried all different medicines like nexium , Gaviscon , Endep- 10 Mg, iberogast.
