Trapped nerve

[El Gordo]

I woke up this morning with a shooting pain in my neck which radiates down my shoulder and into the top of my back. I phoned up the doctor and he says i've got a trapped nerve in my neck probably caused by lying awkwardly in bed. I'm supposed to be doing a run tonight but i'm in so much pain with it there's no way I can do it, has anyone else ever suffered from this? Now i'm worrying incase it doesn't go away in time for Bristol a week on Sunday, it's just typical!

Should be just a short-term problem if it's just from lying awkwardly in bed. What's the latest?
