Had A Fall Over A Year Ago - My Foot

Had a fall over a year ago - my foot rolled on some rocks and when I went down my left leg went forward my right leg went back and I went compleatly down . Ex rays were done recently nothing broken. I still have pain in my groin area and buttocks . Have been in physical therapy the last 2 weeks -2x a week when they started adding a lot of pressure to the top of my leg at the groin area it has made it a lot worse.
