Hi, I'm Almost A Pro Athlete But Recently Some Sort

Hi, I'm almost a pro athlete but recently some sort of knots and a lot of tightness in my left ankle has been bothering me. When I run my calf gets extremely tight. And I also masturbate, I've noticed a big difference after not masturbating for a few weaks my calf automatically is better. So if it is masturbation, then plz tell me the quick way to fix this issue at home .
Thanks
