I had an ACDF with fusion at 3 levels and plating back on September 22. Went back to work 10 days after the surgery. I have been doing fine until the last few days. Waking up every night with serious headache and neck pain. The headache does not want to go away. Does anyone with similar surgery have problems with headaches? I think it may have something to do with the tension form wearing the Miami J collar 24/7. Pain meds don't help the headache. Any suggestion greatly appreciated.
