I have stomach ache right under my right rib cage after eating. I also get swelling of sternum and aches. It is kind of dull pain.This is going on since December of 2011. I had colonoscopy, cat scan, ultra sound, X-rays but they don't find anything. I wake up every night around 3 or 4 am. with gas and can't go to sleep. Also, I have a left shoulder pain and it gets worst when I have stomach ache. Some time I think they may be connected. Some nerve that flares up and passes through digestive system and neck or shoulder. Anyone one suggest something. I had H Pylori in 2001 and most recently October 2021.
