Pain in lower back!

nursegirl79

I have a pain in my lower back. I don't even remember injurying it. It hurts when I sit longer than 5 mins. When I stand up it really hurts until I stretch through the pain and then most of the pain goes away. It doesn't really hurt at all when exercising. Anyone ever have this problem? I don't know if I should see my doctor or not. I also don't know if exercising may make it worse.

Any suggestions?

Thanks
