Hi nicki61400 and Welcome to Healing Well Chronic Pain Forum! You have been given some excellent advice, I have had an ACDF done on both C6/7 and C5/6 like you but mine were done about
25 years apart! I have had two other spinal surgeries since then too! Anyway please don't try and rush it, I can understand needing the money and needing to get back to work, but if you don't heal properly then it could cost you even more in the long run. When I had my first ACDF I was in the military stationed in Alaska, at that time they did not use (or at least on me they didn't) use any hard ware to stabilize the fusion, they just took the bone from my hip and put it in and made me wear a cervical collar for 3 or 4 months! I was off at least 10 weeks before they let me go back to work, and then it was light duty behind a desk and only two hours a day for a few weeks then they increased it to 2 hours in the morning and 2 two in the afternoon, and so forth. Things have come along way since those days back in 1985. Fast forward to 2009 when they did a ACDF at C5/6 and they used donor cadaver bone for the graft and hard ware to stabilize it all, and I only had to wear a cervical collar for a few weeks. I was on disability so going to work was not an issue. I will agree with Snowbunny it takes time for the bone graft to take, and for it all to heal. This is in an area of your spine that you definitely don't want to have problems with! Talk with your doctor and explain what your job is and see what he thinks, maybe he will agree to let you slowly break in, going back to work doing it a few hours at a time. Can't hurt to ask anyway! But please follow his instructions to the Tee!
I wish you well and hope everything works out well for you! And again Welcome to the forum and our CP family!
