I'm narrowing this groin problem down to the cycling discipline. It's when I most notice it... strike that... it's the only time I notice it... primarily when I am at the high poing of my right leg rotation - the last quarter of bringing up the leg and the push down... that seems to be the key to when it's happening and giving me pain. It doesn't cause me pain in my swimming or my running.
It's nowhere near as bad as it was but, like we said the other day, it's returned...
Let me know how you want to progress.
