If you are indeed super active, an in jury that wont clear up can be frustrating.
Understatement of the year 
hy don’t you elaborate on the problem. Give some details on where and when it is sore, what aggravates it etc.
Sure. Injured hip is the right one:
Initial injury was a Friday. I had run: 13 on Wed., 9 mi with two of those miles fast on Thurs., 9 miles Fri and threw in some hills. I normally run flat on the treamdill. It was sore Friday. I’m dumb, so I ran Saturday… 20 minutes easy in the AM and 40 minutes easy in the PM. It was still sore. I think I ran for a couple more days before it became too absolutely painful to run. Yes, this was a dumb thing to do. I already said that.
Initial pain was with hip flexion. That could be something as slight as lifting the foot from the gas pedal of the car to the brake. (If you don’t believe me, think about it when you drive home tonight: there is a little bit of hip flexion.] THAT HAS GONE AWAY fortunately. As has the inflammation over the ‘crease’ of your hip (where torso and thigh meet if you’re sitting). It used to hurt with backstroke kick but I am ok with that now.
I really only have pain walking and running. When my hip is extended it hurts. IE, a lunge position hurts when the sore hip is in extension. So that part of gait in running, where the hip is extended from pretty much when you’ve pushed off with your calf/foot and are trying to then pull your leg forward, is painful. I can pull it forward fine but that extension part hurts.
My left IT band has always been tight and I think that probably caused some of this initially. The spot where the left IT band inserts on the Iliac crest is a bit painful and has been since late July. Maybe that tightness resulted in whatever this is.
The good news… and I am realizing this now that I am writing it and thinking of how sore/inflamed it used to be vs what I can do now… is that it’s getting better.
But it could get better faster 
Does that help at all? Would love any more thoughts. Obviously glute strength + external rotator strength + stretching out all hip muscles and low back and IT band are integral in recovery.
