I am 73 and just experienced lower back pain so severe I had to call 911. At the ER they gave me fentanyl and morphine which took the pain away but I am so worried about a re-occurrence. The MRI shows a 7mm extrusion at L4-L5 affecting the right L5 nerve root. I need advice on what type of specialist I should look for. My family doctor suggested going to a pain management specialist for a steroid injection as a temporary solution, followed by a consultation with a neurosurgeon for long term advice. I have so many question about changes in my exercise routine, how much I can lift, posture advice, whether I should do physical therapy, the likely prognosis to expect, etc. What is the best specialist to find for a general assessment?
