Can muscle repair come undone?

I am 8 wks PO tt w lipo. The past few days I've had some strong pain in my stomach to the right of my bb. It almost feels like my muscles overlap each other and occasionally I have a sharp pain. Is this normal? Is it possible that I my muscles could have come apart? I worry because I had an incision infection that required draining/packing and there was a strange residual pain in this same area. Could it just be healing inside?
