Yes Charlie it does.

In particular since he said nerve ROOT block. What it sounds like to me, and being that the suboccipital nerve comes out of the first cervical vertabrae, he is going to go in on either side of your neck (bilateral) and block the nerve root...that would be C1/C2. Don't worry he will NOT go INTO the nerve he will just block it. That just means they get real close and more or less bathe that area and calm those nerves down. And I can understand why he would give you some light anesthesia. You probably will experience some dizziness right after but that is to be expected since that level is high up there. I had something similar done yesterday only it was the facets at C2/C3. And, yep, I was a bit dizzy but it passes.

IF he had said trigger points or nerve blocks around the occipital nerves up and around your scalp, that would have been different. They still use a numbing med and steroid but the injections are in the scalp more or less. That's why I said they palpate the area for those.

Anyway, when you said "Root" then that tells me he is going exactly where it says...to the root of the problem and those particular nerves come out of that upper level and then for lack of a better description wind in and around the muscles of the scalp. Actually, it should work very well! And you should be sedated enough that you won't even care. Hang in there, I know the injections sound awful but the relief you get, and I just mean myself, is great!
