Had appendix surgery 4/10/12, been 3 months post surgery & i started to feel some discomfort around the top right hand side of my navel area!?

Probably an adhesion: Appendectomy is a relatively simple procedure but occasionally leaves people with abdomenal adhesions, flimsy connections between bowel and peritoneum. These connections are 'normal' but can cause some discomfort when they tug on the sensitive peritoneum, the lining of the stomach. Many times they adjust themselves so nothing needs to be done, .
