Definitely talk to your doctor. If the pain persists don be afraid to get second and third opinions either.
You may have developed surgical adhesions. That is unwanted scar tissue that can build up in your abdomen after abdominal surgery. This is very, very common and usually causes no or only minor problems, but ever so often this scar tissue may grow excessively or bind together parts of your abdomen in a way that causes complications.
I had this after an appendectomy and had to get corrective surgery, but it is even more common after gynecological surgeries such as a c-section. It is sometimes difficult to diagnose, that's why I am cautioning you to not let your concerns be brushed aside by your physician.
Good luck!
