Hey bro. I had c6 and c7 fused back in 1999. Since then i have fully recovered and have been able to lift heavy for years with no issues. Took a while for the nerve to regenerate, took a while to get range of motion back and my neck bothered me for 6 months or so and then i started doing deads and that eliminated the neck issues altogether.
I have been able to PL without issues and reach pr's post surgery.
I am glad I had the surgery and 12 years later I don't feel like I ever had surgery.
Wow, that's good to hear. I have the same issue as the OP, C6-7 and some atrophy in the right chest/tricep. I chose to live with it after all the horror stories I've heard about neck surgery. I might have to put some more thought into surgical options. I suppose it boils down to finding a great surgeon.
