Hi, I was wondering if you could help? I feel like I may have trapped a nerve in my neck? I am usually quite tolerant of pain but I have to admit this is of concern. As I yawned this morning I got a sudden sharp pain in the left side of my head/neck, the type of brief pain you get when you move your head too quickly. Immediately afterwards I started sweating profusely and had blurred vision, seeing stars. My eyes recovered quite quickly, and although the sweating has reduced, the pain in my neck has continued to persist throughout the day. I am able to look to the right without difficulty, however looking left, downwards, and upwards is near impossible. The pain is greatest behind my left ear and radiates up and down my head on the left side. I have taken 600 mg ibuprofen but this has had no impact whatsoever. Is there anything you could suggest to alive the pain? Many thanks, Jen.
