I was also diagnosed with stenosis, herniated discs, etc. I just had a steroid spinal epidural less than a month ago out of complete desperation. I have to be honest and say it helped. Now, it just so happened that the week after I had it, I also discovered Dr. Sarno's book, so it could be a complete coincidence, I'll just never know. Even Sarno said, painkillers are sometimes necessary to start people on the road to recovery - get pain relief enough to stop concentrating on the physical and start concentrating on the emotional - I feel like this may have been the case for me personally. I feel like my steroid epidural was my true wake up call to all of this pain, and the endless doctors visits. Injections were my last step before surgery - which is completely out of the question for me. I have now truly exhausted all of my options from a medical standpoint, so in turn, I became 100% ready for this program. But that's just me!
I would actually hold off on the injection if you can. I would like to have seen if I would have been feeling as good as I have with just the SEP program, as opposed to doing both at the same time. Ultimately, you have to do what's best for you. We all heal differently.
