My only answer would be to contact a peronal injury attorney for a case evaluation.  Have all medical bills, evaluations, doctors reports, accident reports, as well as prognosis available for the attorney.Most personal injury attorneys will grant you a free consultation and evaluation.  You might have a claim for present, as well as future damages.  I have no was of knowing. Get a professional legal opinion.  If you sign a waiver, you are giving up many or your current and possible future rights to recover.  Get legal assistance.
