so this is a serious thing? I asked my Dr. in 8th grade and he said growing pains and they would go away after a couple months.... Both my knees pop when i crouch/squat down, and my elbows, back, wrists, fingers, toes, ankles, and oddly enough my tail bone pop. My ankles pop with every step. Im 26, and don't lift anything besides parts at work, i played football from 7th-9th grade and was in marching band in high school...
(enter band camp jokes/ the buster here)
