There's a pain in the upper left side of my stomach & it hurts like punching a fist thru it from the inside. I have a duodunal ulcer already and it is not that kind of pain. This happened after I had a breast reduction but my surgeon says there is no way it it related and it is a stomach problem maybe collitis or diverticulitis  I have no bowel problems, no visible blood, or any other symtoms, just the uncomfortable pain.  It also goes straight through to my back which feels like a back ache.The surgery was a month ago. I am female, in good health, 41 years old.  I am also dealing w/ an infection from the breast surgery which the surgeon classified as cellulitis. Again, the description is pulsuating pain like someone is trying to push their fist thru my stomach. It bothers me when I eat generally. Any advise would help if someone has experienced this before. Thanks.

Summarized question: Does anybody have experience pain in the upper left side of my stomach after breast reduction surgery?
