See below: Problems like these can only be correctly handled by your doctor in person. He/she needs to listen to you, perform an examination and possibly run labs or other tests. That's the only way he/she can find out what's going on and what to do about it.

Ulcer or healing: Pain in the middle of your stomach could be an ulcer or stomach irritation. Of course many other things are possible like simple healing pains, constipation, gallstones. Best to contact your surgeon.
