I was playing hockey and when i went to shoot i felt a sharp on lower right side of stomach. it felt like something tore or popped. now it hurts when ?

Oblique strain: With a slap shot u wind up twisting us torso away from the intended direction, then during the shot u violently contract the oblique abdominal muscles to get the velocity of the shot. This sudden acceleration with the muscle @ full extreme of stretch can b strong enough 2 cause a strain. Grading is 1-3. 3=severe muscle damage ; lead 2 a long recovery, 2=less so, 1=minor ; short recovery. Good luck.
