Just had an S1 nerve root block last tuesday after the painful butt pain/pinching. After immediate relief for less than a day, it wore off and I'm back to butt pain again, so that makes me wonder if the relief came from the initial anaesthetic not the nerve root block.

Any ideas what these clues might indicate? It hurts when I stand, lie on my stomach or lean back - when the pain in the butt increases. I can sit without much discomfort.

I've put an ice bag on it for a long time and there's no relief from that.
