This week I noticed after I did leg press that I felt some pain in my lower back whenever I twisted my torso. Also when I bend over, raise my right leg(in the manner of putting pants on or going up stairs) or cough or sneeze, I get a shooting pain in my lower back, and upper right glute, and it wraps around to the side of my right hip flexor area. Anyone have back problems before and know what this could be?
