Anyone contemplating this treatment should be aware it can go awry. Several years ago I was scheduled for one, my first, for severe back problems(spondylolisthesis and associated problems). When the doctor inserted the needle, it sent my whole nervous system into shock. I told him and he asked me questions. After about 5 minutes he asked if I wanted him to withdraw the needle. Duh! I thought he had already removed it. Never did get the injection. They gave me a pain pill, and ended up taking me to the car in a wheel chair about 45 minutes later. It was awful. Things were a little better until I woke up in the middle of the night to go to the bathroom, and I couldn't get out of bed for the pain. My husband helped me call the doctor's emergency number and I got another doctor who was on call for that office. He said, "Oh yes, that happens some times and it will take a while to recover." The doctor who tried to give me the injection, said he had never heard of such a reaction. A physical therapist later told me my spine must have been "really hot."
It did take me two months to fully recover. I had to sleep in a big recliner we had for about 10 days as I could not get out of bed. When I awoke, I had to take two hydrocodone pills, and wait for them to take effect before I could get up. It was awful.
My primary care doc sent me to a wonderful pt specializing in back care and he got me out of my original condition. I will never have an injection like that again.
In addition, I am very circumspect about having any medical procedure or other treatment. I try to get all possible relating information and weight carefully before proceeding.
Keep it under control!
