Sharp muscle pain in lower stomach

I was banded on Nov. 15th. I noticed post-op that I would get a sharp pain in my lower abdomen when I bent over too far. I figured that was normal right after surgery. It has happened less frequently now, but I still get it at times. Usually when bending over or at a specific "intimate moment" with my hubby. It's way below my port. It's below and to the left of my belly button. It's definiately a muscle pain. It's very sharp like a cramp and really hurts. Does anyone else have this?
