Hi everyone, I am having 2 sacral nerve blocks (S2/S3) to try and identify the source of my buttock pain. The Dr thinks I may have Posterior Femoral Cutaneous and Middle Cluneal nerve pain. Since I got home, I have been researching these nerves and see that they can come out of S1 and S4 as well. So my question is, which nerves can you be certain to have blocked if S2 and S3 are blocked. I know there must be reasons for only blocking 2 nerves, but wondered if anyone could shed some light on it for me. Also, for the purposes of diagnosis alone, I have been thinking of just taking the anaesthetic and refusing the steroid. Has anyone done this and is it wise? Many thanks for any help anyone can provide.
