Do I have a malpractice case from digital median nerve damage caused by a botched carpal tunnel surgery?

A Neuroligist identified digital median nerve damge following CT surgery. Medical records from MD office are inaccurate & downplay intense pain and distress 5 and 7 days post op. I think he's trying to cover it up. Never saw MD againl he hid behind PA's and had 4 brief phone calls. I suffer from intese burning/shock like pain with minor touching. Refered to hand specialist & he confirmed this is NOT from carpal tunnel. It came from the surgery. Had reconstructive surgery with hand specialist 7 months later. He observed massive scarring & stated "In my gut, I know it was cut." I am a teacher; this has caused problems at work & I struggle to correct papers & do my job as this is my dominant hand. This has been a life changing injury. Is there anyone that can help me? We do not have the funds to pay for a expert examination of records, etc...
