I have had nine sets of steroid injections and have had very little pain relief. Don't ask me why I tried nine times! One doctor said that the last doctor just didn't do it right so I gave him the benefit of the doubt and agreed to the treatment. Well, three days ago I had a rhizotomy and am in more pain now that I was before. I am wondering if anyone can tell me how long it will be before I feel some pain relief. Thanks in advance for your info.
