I definitely recommend seeing your primary care doctor
as soon as possible, because the pain sounds quite severe and it should be addressed. In the meantime, if you experience any warning red flags, such as blood in the bowel movements, fever
, worsening pain, or severe nausea and vomiting you should go to the emergency room for immediate evaluation.
There are several possible explanations for the pain you are experiencing, including simply heartburn or gas pains. However, given how severe and episodic the pain is, I would also be worried about gallstones or an inflammation of the gallbladder, particularly if the pain is worse with fatty meals and also causes bloating or diarrhea. Pancreatitis, or inflammation of the pancreas, would be another possibility which can also be related to gallstones among other things. Bad chronic constipation can also lead to episodic abdominal pain and a sensation of fullness. Finally, an inflammation of the lining of the stomach (gastritis) or a stomach ulcer
may cause pain like this.
As you can see, the list is long, which is why it is important to get in to see your doctor to see if a diagnosis can be made.
