I just had ACDF for a C5-6, one disc. So far so good. Some days the "charlie horse" feeling comes back in my elbow, and the back of my neck feels the same pain as before (I slap on a Salonspa patch to dimish the pain) but otherwise, I can tell the good it has done for me, even now, at week three. I am thankful for the Doc's skill and my body getting this under control. Now the bad news, Last year I had a lumbar disctectomy, that did absolutely nothing except relieve the right leg droop. Did nothing for the left leg or the excruciating pain for the lower back. Cannot walk more than 10 mins, without pinching beginning and back swelling and a terrible raw sensation. I have a great Doc, he just does what I imagine others do...says, he does not know why. Simple tasks, like cooking dinner and cleaning, shopping, create havoc on my lower back. I still, as you can tell, cannot accept that this is happening to me.
