<s>[INST] my husband had an inquinal hernia operation 6 weeks ago and all was fine but he noticed swelling in the groin and went to his gp and he said one side of the mesh has come away which very rarely happens he has to go back to his surgeon july 9 as he is on holidays at the moment will he have to have the operation again [/INST] Hi, usually pre- and post-surgery one needs to learn some simple abdominal strengthening exercises. Which can keep the mesh in place. Requirement of doing exercise came into existence for early and long term achievement of the surgery from couple of years. Why don't you just try looking for a physical therapist and undergo some small simple abdominal strengthening exercises. Once the abdominal muscles become strong the issues of the swelling in the groin should come down. As abdomen is divided into 9 different qua Chat Doctor. I wish you a speedy recovery. Thank you </s>
