I see one of the best spina surgeons in the USA~ he works on California 49er football team injuries. I did every injection, spine therapy, pain killer for 10 yrs. A dr wanted to do a lower lumbar fusion. I went to the dr above for a 2nd opinion and I am so glad I did. A 10 minute exam revealed most of my pain was being generated from Facet Joints and not discs! Yes I have degenerative disc disease, leaking discs, arthritis and a few other big words but… can your pain be produced when someone pushes on your spine? When you sit up against something does it hurt? You see… my dr sad that disk pain comes from within and cannnot be induced by physical exam and that was his clue to Facet Joint pain. This is important because 1. If they can perform a Neurotomy (burn some nerve pain sgnals) and reduce your pain 50% or more~ would u be “fused”? 2. My dr said that DDD is progressive and fusing the lower 3 or even 5 will ultimately cause collapse of those above s he won’t fuse any DDD patient unti 7 discs are bad. I am recovering from my 7th nerve burning in 8 years. Well worth it!
