Hi, thanks for writing to HCM.
In general, the pain after ACDF is supposed to get better as the time pass on (within a few weeks). A Hard cervical collar
is a must for atleast 2 months till the time the graft gets incorporated.
After completion of 8 weeks after surgery, you are supposed to carryout all activities without any issues. All the radicular pains (shooting pains) in the arms should get supposedly reduced within 8 weeks.
Hope this information is helpful. Good day
