Has anyone had a spinal nerve root injection? I've been having severe back and leg pain and have been diagnosed with degenerative disk disease, spinal canal stenosis and spondylosis. Tomorrow I am scheduled for a nerve root spinal injection and I'm very anxious about it. Let's say I have a low threshold of pain

. My husband is driving me and the doctor is having me take a Xanax an hour before the shots for anxiety. I'm wondering if any of you guys had this and if so what can you tell me about it. Thanks for any information you can provide.
