Non-healing quad pull

[KnottedYet]

Is it a quad pull, or is it a pronated foot/medially torsioned tibia/internally rotated hip?

sounds like all your activities are fine, until you get to running. Are you doing any other high-impact stuff? (jumping, jump rope, hopscotch?) Does it hurt, too?

(if you look at an anatomy picture, is your pain in the neighborhood of vastus medialis obliquus?)

It is actually exactly where my vastus medialis is. The pain actually runs in a line down my quad in that location.

My hip isn't rotating medially, if anything it rotates laterally (turn-out from ballet). My running shoes were pro fitted and from what I can tell I'm not pronating now, but I have a tendency to if not in proper shoes due to my arches collapsing. I've never noticed any type of tibial torsion, but I haven't had that checked out by any means. One problem I do have is a slight leg length discrepency, with my left leg being about 1/2cm longer.

Running is the only thing that hurts now; well, after aggravating it yesterday it is sore with pretty much anything, with occasional pain. Biking bothered it right after I injured it, but hasn't since taking a couple of weeks off. No other high impact activities, but I do horseback ride and jump quite a bit, but that has never bothered it, but that uses the adductors more than my quads.
