I had the surgery on 04/07/10 and since then have been having a stabbing pain in the middle of my stomach towards the left side. I passed all the tests before i left the hospital and was perscribed medication, but the pain will not go away. I am drinking fluids well and have not thrown up except for dry heaving right after surgery. I just want to know, is this normal or did i make a big mistake. Any assistance in this matter would be greatful.
