Today I ve woken up with pain in the lower right side of my back. I figured it was just me sleeping wrong so I ignored it. It hasn t gotten any better throughout the day. I recently spotted a dent on the surface that has been giving me pain from whenever I move. I m thinking it has something to do with my muscles? Yesterday, I ran an indoor 10k race, which constisted of 56 laps of continuously turning right. Each turn on this track was elevated as if it were a nascar track. Could this pain just be consequences from running on this track?
