Let me see if I can make this clear for everybody.
Negligence cases against doctors is just as tough as a med mal case... the "DUTY" that asiansINC pointed out... isn't an absolute duty to make sure they did the procedure (whichever doctor it may be), but it is a duty of a reasonable medical professional in the same area of practice... now, if a reasonable medical professional would have done the same thing he did, and the result was that you were still awake... then there was NO BREACH of that duty, even though you were awake and felt the pain... because there was NO NEGLIGENCE.
Forget about Med Mal... it doesn't even matter if you have evidence of an injury... if an reasonable doctor in the same situation would have acted within the same scope of actions... then you suit will fail.
Doctors are held to a high standard, but they have a pretty good defense of the "medical community" -- being that they practiced the same way that other professionals, and followed all the guidelines and followed every precaution... you're fucked.
Rack it, stack it, anyway you like it.
Now, you might want to consider loss of consortium... if you have a wife or have lost sexual appetite...
