Hi all... new here. First let me start by saying my health insurance sucks and that's why I have seen a Dr yet. Anyway, everyday I have a constant tightness in my lower back almost in my butt and it's like an achy kind of feeling all the way down my leg. It makes me want to do nothing at all except sit around. It feels immobolizing and I have to say I'm alittlw scared. I don't think it's sciatic cos it's not sharp shooting pains. Just not sure what it is..any thoughts?
