So yesterday, I was at school. I was heading to my class after i ate lunch and dropped my backpack off, and after I did, I started off to go find my friend. But, like, 2 feet from my bag I got this sudden, sharp pain in my lower back, like waaay lower. It hurts to bend forward and move a little, but thats about it. Alot of people are suggesting its my backpack and the ungodly amount of textbooks in it.
I just wanna know if this is serious or some stupid back injury that just happens that I havnt had happen yet.
