Do I have a case

Hello Denise,   Sorry to hear and hope you will recover fully. When you are rear ended, it is presumed you are not at fault.  Reach out to speak with Personal Injury/ Car Accident Attorney. We are unable to solicit. However, we all provide complimentary consultations. 

Rear End collisions are almost always the fault of the driver who collided with the vehicle in front, so you have a case. Retain counsel here in Florida on contingency fee which means you don't pay anything unless you win.
