You can have someone be paid a fist and lightly touch it on ur lower back side (both sides). If this maneuver elicit pain, it's call costovertebral tenderness, and indicates the presence of kidney stones. Have u be having any disorientation, nausea, vomiting, pain urinating, constipation? Ask urslef these question. It may ofcourse just be muscle strain, but u never know unless u budge to ur doctor. Good luck and take precision!
