question: Hello doctor, I have a 4 weeks old baby boy. He was healthy without any pain or colics. But yesterday I noticed a swelling in his inguinal area, I went to the hospital, and the doctor said he had left inguinal hernia. But it is not bad. The problem is he is not taking feed regularly, and when I try to feed him, he wants to eat only when he is hungry. But he cries. He vomits four to five times or even more after feeding and also has a lot of hiccups. I feed him in the upright position. His stomach looks like a balloon, and he is having a problem to excrete. Can it be a reflux or lactose intolerance? I told the doctor, but he said it is normal. It does not seem to be normal because the baby is uncomfortable and always arch his back, and he is always grunting as he wants to excrete.
