2 years ago i was on a exercise equipment where you hold on in fromt of you and bring both your feet outward as far as you can go, i did it too far and felt pain in the groin i was fine 3 months later this started i also at times hear a click in the groin,,cant walk far if i do it hurts and it feels like my thigh is swelling
