My back

I went to the doctor again today because a nerve near my back is really hurting. He says it is my sciatic nerve. He had given me trigger point injections for my back pain that I had 2 years ago and that had kept me pain free until now. But this last month I have developed this new pain with my nerve which I have never had before. He did not have good news for me...he says since my MRI of 2 years ago was so bad, it looks like my back is getting worse and trigger point injections are not an option for this new symptom. He ordered another MRI and ex rays. He said I might need surgery if something shows something on the MRI and ex rays...I couldn't hear much of anything he said after the word surgery, my eyes were starting to well up and I was feeling a little overwhelmed....I had the ex rays today and the soonest they can do the MRI is wednesday because that is when the MRI machine comes here to this small town. So I will know more after Wednesday. I guess I could see if I could get the MRI done in cheyenne sooner than that....anyway the prospect of surgery on my spine is very depressing...as is the news that my last MRI was very bad. No one told me in that way before about my MRI that I had so I didn't realize it was that bad. The exact word he used to describe the MRI of my back actually was "nasty"
