Hi
Welcome to health care magic.
Pain in the stomach in between meal .
If I were your treating doctor for this case of pain the stomach I would come up with these possibilities , these include:
1 The first possibility is of
peptic ulcer disease or
hiatus hernia.Diagnosis can be confirmed by upper G I Endoscopy.
Try raising the head of your bed about the 4 inches with the blocks. It also might help to avoid eating or drinking for two hours before you lie down.
To help control stomach acid one should not drink alcohol or drinks with caffeine in them or eat chocolates or spicy or greasy food .
Also take some antacid but if symptoms are sever you may need drugs like PPI ( like pantoprazole+
domperidone).
2 The 2nd possibility is of
pancreatitis as it may cause upper left
abdominal pain which is worse when bending or sitting .
Pancreatic enzyme like serum amylase & lipase should be measured to rule out pancreatic cause.
3 Sever stress or anxiety is another reason of such pain, so be careful about that also.
Deal as mentioned above.
Hope this information will be useful for you.
Further , if any question I will reply happily.
Good luck.
