hi numb,
Do you have all the details written down and is there any notes from the drs or staff or witnesses at the time?

From watching lots of the TV court shows -I'm just thinking that there would need to be some sort of evidence & paper trail??
Something documented by another dr? That you were OK until right after this procedure.
Have you consulted with some attys to get their take on it?

You can also check your state website - medical board section and see if any of the drs have had any problems or disciplinary actions.
