My air bag deployed while driving to work about a year ago, just below my rib area, was very bruised and sore, I have been having abdominal pain, headaches and nausea. A recent CT scan showed contrast on the spleen the radiologist said it had the appreance of a cyst and that they wanted to keep an eye on it and do another scan in a month, my question is can an airbag cause a spleen cyst? I didn't tell the gastrologist I had been hit by an airbag.
