The doctor's credentials are well-known to Taylor at this point and he allowed him to perform 2 nerve blocks in the days preceding, without incident. What he's trying to claim, as I alluded to before, is that by changing the concentration and/or amount of local anesthetic, it was battery since it wasn't a procedure he (would have) consented to and it caused the complication. Neither is true and it's amazing the case is being allowed to continue.
One thing I'm not clear on, and I may have missed it, is did the insurance company offer a settlement? Or did they not want to settle at all?
