Hi, How are you? My name is Dr Suresh Raghavaiah. I am a surgical gastroenterologist and I hope to answer your question today. I am sorry to hear about your pain. I am sure that you have undergone a Laparoscopic Cholecystectomy. This usually involves making a incision below the belly button to insert the camera. This usually ends up being the biggest incision of the 3/4 incisions made to remove the gall bladder. Normally, this incision is closed using suture material after the surgery is over to prevent a hernia through the incision. Sometimes, some surgeons leave it open, especially if the incision was a small one. The pain and bruising you talk about could be one of two things. You might be feeling the knot of the suture material which was used to close the incision (Rare if absorbable suture was used, a definite possibility if non-absorbable sutures was used) or it could be a small bit of omentum which has herniated through the incision. A simple ultrasonography scan of the belly will make the problem clear, so you can manage it appropriately. Hope this helps and hope you start to feel better. Please do not hesitate to write back for clarifications Have a great day Dr Suresh Raghavaiah
