i had a hip replacement done two yrs ago and now I suffer from Heterotopic Ossification, can I sue the surgeon for the pain I feel?...

I am sorry to hear about your problem.  By any chance did you have a metal on metal hip or a device by the company Zimmer. These devices are sometimes dangerous and this may not be the surgeon's fault.  Please feel free to contact me at ryan@koesterlawllp.com or call 217-337-1400.
