I am really glad to hear the pain pump works for you. That is always fantastic news. I did read up on myelomalacia, and this really is something I would investigate if it were me. Maybe seek another opinion. Your case is complicated. Going through the front, for the cervial spine is what I did.
I did read that spinal stenosis can cause myelomalacia, and that it narrows the spinal cord. I sure am no doctor, but the condition may warrent another opinion. I hope you keep in touch with me and let me know how you are. Wouldn't the pain pump take care of the majority of your back pain? I hope that you get permanent good results, and that myelomalacia does not turn out to be anything bad to add to your troubles. If you google that word, there are many sites about the condition. I wish you all the best. ginnie
