I had neck surgery just over 3 month's ago. Now I am getting severe headaches. The fusion was of C4&5 5& 6 .. My fusion took and is healing well. The only problem is now I'm experiencing bad headaches on top of my head towards my forehead and in my eyes. Anyone else having this problem. I have to stop them . It's making everyday life harder than ever now. Stress headaches and tension. I'm wondering if that's the problem now.
