no haven't found exact solution but its a year on now and it's much better. I'd suggest rest it for a while and then start building it up in gym once you feel up to it. It will get stronger. I'm not playing footy at the moment because of a back injury (another suggestion; don't try and compensate for injured groin/hamstring, it will go straight to your back! So mind your back), but my groin feels well up for football if i can get my back right. hope this helps....
