Hi there SJH,
I was breezing through and saw you had a post without a response. I truely understand how you feel. That is an awful lot of money to be put up front without any guarantees and you mentioned they didn't check your cervical and lumbar spine, which maybe I am not familiar with your circumstances, but it just sounds odd. They may be fine, but I always feel uncomfortable when places of business want the money upfront.
I have had quite a few epidurals and nerve blocks and never got relief but I have heard of others who have and even someone that had it done and his pain was gone for good!! Imagine that!
I am sorry I can't offer you much on this, maybe others can. I know that they didn't help me but I have heard that others found relief for different periods of time and one person said it took the pain away. I know when you are in pain, you want to try anything to get relief. I truely wish you well and hope you do get relief somehow.
