Welcome to healthcare Magic!
The type of abdomen pain you are having can be due to many causes.
It can be due to innocuous causes like acid peptic disease
, irritable bowel syndrome
etc when all scans are normal. But it can be due to some serious possibilities like cancers, diverticular disease
, crohn's disease, gut ischemia
You should get a thorough examination and work up by an experienced physician of your locality and get investigated as soon as possible.
I hope the advise would be informative and useful for you.
