Hi,I had a car accident 3 wks ago.When I first got to the Hospital they were doing everything right.they started an I V,they took blood and they took Chest xrays ,Then they injected a dye for a CT Scan.The pain was so bad in my Sternum,but the Dr, said the tissue was very swollen but the could see contusions ans bruising between my Rib Cage and lungs,also swelling in my left lower Lobe.Told me it would be very painful for quite awhile and follow up with a Surgeon.Could my Sternum be broken?
