Neck injury...seeing a doctor vs. home care? Please help?

Today, I took a plunge down some stairs. My neck immediately started to hurt but I was able enough to move my head and whatnot. I believe what exactly happened was when I slipped down the stairs my backside took the grunt of the fall and the back of my neck hit each step. It is a few hours later and the base of my neck seems to really really hurt. It hurts whenever I turn it and even just sitting around it just...hurts. I'm wondering if I should be concerned enough to see a doctor? I just lost my insurance so I really want to avoid going if I can. I don't know whether it could be a strain, sprain or what have you. Any advice would be great. Thanks!
