2 weeks ago I was playing kick ball and I kicked the ball and felt a shooting pain in my right hip flexor, but I waved it off and kept playing. 2 days later it hardly hurt so I figured it was better. Then when I went to squat on my max effort lower day it hurt like a mf coming out of the hole. I tried squatting again the next week same issue and then today same issue. Any advice on what muscle is probably strained and how to rehab it.
