Sounds to me like you need to be strengthening. Including strengthening exercises will greatly reduce the liklihood of a return of your symptoms once you return to sport. If running is causing you pain (or resulting in increased pain after) then you need to stop.

The main areas to strengthen are your groin muscles, and pelvic stabilisation muscles. Once you have worked on strengthening for a couple of weeks you can attempt to run again but the same rules apply - any increase in stymptoms and you need to stop.

I have some strengthening exercises which I can send you via email if you are interested. Let me know.
