I was in a car accident. I was in the drivers seat and was hit at a high speed squarely on the passanger side of the car. I had a Hiatal Hernia before the accident but now it actually hurts and I can feel it almost all the time. Could it have been aggrevated form the seatbelt during the accident?
Hi and welcome to Chat Doctor. Thanks for the query. Yes. Raised intra-abdominal pressures which can be seen in such trauma can cause aggravation of previous hiatal hernia, and it may be what you are experiencing. It can cause stomach pushing more to thorax.  You should do gastrostomy and barium swallow to rule out this so that appropriate treatment can be considered.  Wish you good health. Regards
