When can I expect to feel pain free in my neck muscles after having ACDF with a titanium plate almost 6 months ago? I did wear a hard collar for 6 wks. post-op and did PT for a month after that, I also continue to do the stretches sent home with me everyday.  I had two ruptured discs c-4 and 5 for quite some time and did not know that was the cause of my numbness and pain in my arms prior to being referred to a neurosurgeon.
