[|Human|] my son has internal chest/abdomen pain which doesnt feel too bad until lying down, laughing, sneezing...Started Monday and gradually getting worse. He is 19, fairly fit and has increased his weightlifting activity over past couple of months but had not done any lifting on chest for over a week.....what could it be?
[|AI|]  Hello, Welcome to Chat Doctor, As your son is doing a lot of weightlifting he is putting a lot of work on the muscles of the body. As most of the weightlifter do lot of chest and abdominal workout, it will put a lot of load on the muscle. While doing this the abdominal and thoracic pressure will increase which may lead to pain. While laughing and sneezing pressure in the abdomen increases which will leads to the abdominal pain. Hope I have cleared your doubt. Hoping to see more queries. Thank you.
