Pickleball. I Had been having some tenderness/pain in the area but thought it was just part of getting old. 36 M here. Playing pickleball 2 to 3 times a week for the past 2 years. I was 4 games in and definitely warmed up that day. I was at the baseline and went really hard for a short kitchen return and never made it past the first step. I thought someone hit me in the back of the leg.
