rock, I have that hip snapping thing..the snapping itself wasn't painful, just annoying...but then
Bill, I got lazy with my stabilization, like you mention above, and started doing some running intervals again last week (mostly because I was feeling better) and am now hurting again. The snapping doesn't really hurt, but the Thomas test or pushing my knee inward while sitting does. (don't ask my why I was doing that, but I just did..was sitting in my desk chair, leaning over and pushing my knee inward)
Maybe I just started running intervals again subconsiously so I'd be in pain during the retreat so it would be easier for you to see what my problem is

...that is if you don't start running away as soon as you figure out who I am
foam rolling the whole groin area (my pain is more towards mid-outside of front part of hip) a good idea still?
