Today at cheer practice my lower back started gradually hurting more and more, by the end of practice it actually hurt bad to walk and get in the car. My assumption was that I had over strained my back over these past weeks of hard work and lifting girls in cheer... why does it hurt this bad though? I immediately tried my best to get up the stairs, ice my back, and take Advil. It has been 6 hours and my pills have not worked. Anybody know what this could be or why it's such in intense controlling pain?! I can hardly walk to the bathroom
