The causes of stomach pain after a car accident can range from mild to severe. Stomach pain can be caused by muscle strains to the abdominal area. But in more severe cases, it can be caused by internal bleeding or injuries to the internal organs. In many cases, abdominal bruising after a car accident can be a sign of a serious internal injury.
Many of these injuries occur due to force exerted onto a seatbelt during a collision. They can also be caused by abdominal impact with an airbag or being thrown around during a side-impact collision or rollover.
