A few days ago my lower back has been soar. It's not a sharp pain that restricts me from standing up. I actually Skateboarded with it yesterday just fine. And didn't notice it til I got home and sat down. I've had a soar back before that was way worse and made it really painful to get up. But this one isn't a serious pain. I think it could just be from sleeping on my bed weird. I have been waking up in weird positions lately. And I sleep on my side which I've been told can cause back pain. My bed is a normal mattress. Like I said the pain isn't super restricting. But is an inconvenience. So sound like a more normal bed related back problem? Or something different? The pain is in my lower back and sort of above my tailbone, at the back of my waist.

I know of back problem related things like kidney stones, And so far I have not had blood in my urine. My urine is normal. And this pain has been going on for about 3-4 days I'd say.
