Abdominal pain after appendectomy

Dear Ask The Doctor: I had my appendix taken out 3 weeks ago along with a hernia behind my belly button , i have been having stomach pains lower and upper along with burning sensation need to know if i should call my surgeon or what to do

Dear Nate: There are numerous causes of abdominal pain, some that may be explained by complications of your previous surgery as well as some which may be entirely unrelated. You should return to your surgeon for a checkup. Complications of your surgery which may cause abdominal pain include adhesions or injury to surrounding organs during surgery. However, these complications are not very likely to have occurred.
