Dealing with Neck Pain

So I am dealing with a pinched nerve and strained neck from a collision and subsequent header on the soccer field. I played about 10 minutes in my co-ed game but it was intense pain with every step as I ran. I have an indoor game tonight...I am feeling better but it is far more competitive...we will see how it goes. I want to be able to run again, but am thinking it will be a good week or two before I can even do it..and two-three until the pain subsides.
