Welcome to Neuro talk. I came here with the very same concerns you have. I was freaked out, crying, and not reallly in control of myself due to the pain.
My first surgery was C6-7, I thought I was done. Wrong.... long story but I am now fused C 3-7. It was a long recovery, and it was painful. The meds given were pretty goo however and I got through it. I started PT at 4 weeks.
If you choose to for forward, please make sure you go for that second opinion, and be absolutely sure you want the surgery. bring a list of questions to your doctor, and make sure What medications he will prescribe for you, and all the What if's explained. No it is not easy to go through, but the outcome can turn out OK, even with the second round of fusions. Keep coming back here for support. You will be OK. We are here for you and so am I. ginnie
