I Have Get A Pain On Inside Of My Right

I have get a pain on inside of my right upper leg near the groin area. It feels like something locks up in that area and then pops loose. Then it hurts for a few days and stops. Then I will be walking thru the house a week later and it happens again. When it happens it stops me cold and I have to limp and push off the side of my foot to control the pain. It make me think of sticking a stick into bicycle spokes.
