I am not completely new to spinal surgery or fusion. I had L4-5,L5-S1 removed and fused in 2002, I am not going back for an issue at C5 that is causing complete numbness of the left arm. It is so bad that no treatments were given before the surgery. Pain, seen dr, had mri now off to surgery on Thursday. I trust this doctor greatly but I am still afraid of not regaining full function on my arm. They said it might be 3 to 4 months before the true outcome is known.
