I had decompression surgery 6 weeks ago. My recovery has been going well until this week. I noticed that my headaches were very severe in the mornings and that the back of my neck is swollen. I am going back to my neurosurgeon tomorrow morning. I don't have anything leaking but my neck is definitely swollen on the incision site. I know I could have a CFL but has anyone ever had these symptoms without a CFL?
