I have had numerous rhyzotomys (7+) over the course of 9 years following 360 ALIF/PLIF lumbar and then SI joint fusions to relieve nerve pain from spinal instability issues. Sometimes it works, other times it's not as effective. It really depends on whether the doctor treats the correct offending nerves. This highly depends on the patient accurately describing their pain and limitations. Also remember that this can be temporary as nerves can regenerate and the problem will return. I understand that some nerves that do not impact major muscle function and can be permanently removed and I am exploring this as a more permanent fix. I have also tried prolotherapy, acupuncture, epidurals, nerve blocks, and numerous PT sessions, etc without significant longterm relief. My goal now is to focus on reducing the number of rhyzotomys I need annually to have a "normal " existence. After a rhyzotomy I feel well enough for a normal outing like going to the zoo or boating. Before the rhyzotomy, I can barely make it through a Costco's grocery trip or get out of bed without assistance, stairs are almost impossible. If you have problems on both sides, know that they only do one side at a time. So you may feel like a car that only got one flat tire fixed and the fender is still falling off the other side that still running on a flat. Hope that makes sense.
