If the people you’re seeing can’t give you a clear answer other than overuse, I’d find someone who can. Maybe the block or the sprint caused it. Maybe it didn’t. Why did it go away and come back? Did the people who have evaluated him done full body evaluations? The chiro that fixed my sons back could see from a video of him throwing a weak area in his core that was disrupting the chain causing other parts to overcompensate. And he isn’t a crack your back type of chiro which I thought was weird. But the guy knows his stuff. If they are only looking at his hip they are probably missing the overall cause of the injury.
