I am sorry you had a car accident. You report that your car was tootled but you are basically OK, thank g-d. Now we are concerned with how your chest feels and your breast implants. Best examination to determine if there is rupture of your implants is to get a bilateral MRI of your breast and chest. This could also tell us if you have a cartilaginous injury of your chest, a chest X-ray will only show fractures of the bone. I have had one patient who was saved by her implants, she had bilateral rib and clavicle fractures with ruptured implants. I replaced the silicone implants some months after the initial injury that required Intensive care and respiratory support. The silicone implants had acted as shock absorbers, so she survived, the driver was not as lucky.See a board certified ASAPS plastic surgeon with breast implant experience. I hope you feel better. Good luck...
