I have an upcoming appt with my pain management doc on the 19th to discuss the 2 ESI's that I've had in the past month and a half. I think she wants to discuss whether or not to do the 3rd injection. I have been doing some research on nerve blocks and it seems that I may be eligible for one since I have had 2 ESI's with no relief. My most severe pain is in the lower left side of my back and radiates to the front of my left leg and hip. It's not sciatic pain down the back or side of my leg but more like a deep ache that feels like my bones hurts, kind of like a tooth-ache type pain I might say. I was wondering if anyone has had a nerve block that is willing to share their experience with me. Thanks. Lauren. :?
