why does my back hurt?
Hi, I am 18, a guy. my back hurts for no reason, whenever I wake up in the morning (I sleep on my stomach) my back just hurts. I can t get up in the morning without it aching, it feels like a sharp pain when I wake up. could it be from my workout routine at the gym? I run 2 miles and do 80 pounds of upper body. whats wrong with my back?
the sharp pain is in my lower back
