They could use a local for a FNB, but in all liklyhood to get the area completely numb, they would have to inject in at least 3-5 sites around the node and in it. The FNB will only be a couple of pokes with a similar needle. So why get poked even more? After what you have been through, this is a cakewalk. It will be over in one minute. Best of luck, and remember that PETS put out a lot of false positive. Hopfully this will turn out to be one of them.
