Hi Ginnie, thank you for replying to my thread. I have been googling most of my results and it does help but it does not seem to inform me much about nerve compression. When I told my consultant about all my pain, tingling and numbness including a crawling feeling in the back of my head, he said I may have fibromyalgia. I looked this up to see what it is and there were not many matches to this condition. Surely the injections wouldn't help if I did have this? I have also been suffering with bladder weakness which can be a symptom of DDD. You say you had a 4 disc fusion - wow that must have been tough to go through. Does this mean you are unable to move your neck? Has it helped a little? I wish you all the best.
