If I have the pain first thing and take paracetamol it goes for the rest of the day and doesn’t return, that’s just one 500mg pill. I have wondered if a nerve is trapped. I have creaks and crackling inside my head when turning it or nodding, the doctor felt the movement and said almost certainly (at my age) arthritis…..which I kind of thought it was. I asked if this could cause the head pain, as all nerves in your head go via the central spinal canal and she said it was a possibility but kind of discounted it. I’m seeing her again tomorrow and am going to ask for another MRI as it’s about 15 months since the previous one. Perhaps a neurologist could help….. I’m all out of ideas but keep worrying.
