Pain after running

admmommy

I have been working towards finishing my C25K and I started week 7 this week and I was only able to do the first day. I thought that since I signed up fora 5K that I should start running outside because the first 6 weeks have been on a treadmill. So long story short I ran up and down my road for 25 minutes and ever since then my neck has been hurting. Is this something that will pass or do you think it requires a doctors visit? I am afraid to run outside again. I am starting to get discouraged
