My son had hernia surgery in January. He has been hospitialized nine times since the surgery. He has abdominal pain and vomiting that usually last two or three days. He ended up in the hospital before he ever made his one week check up after the surgery. The doctors keep saying that if the problem was from the surgery, he would have a really swollen, red, infected looking place. They have run every test that they can run, some even twice. They keep coming up with nothing. I thought maybe they were right and something else was wrong and the timing was just odd but when they don't know what it is, I have to wonder if it is from the surgery. Has anyone had this problem or have any information? Thanks for your help. Diane
