I am thinking it is the pectineus or adductor longus after looking at some anatomy drawings. I performed a pectineus stretch and I feel the stretch in the affected area. The "injury" affects me mostly doing mundane things. Such as when driving, if I shift my pelvis back by pulling with my glutes, I can feel the "pinch." I also feel the "pinch" if I bend over that leg to pick something up. The most aggravating thing is it doesn't hurt all the time and flares up just as it seems I have forgotten about it.
After reading this:
I am convinced it is one of those three muscles.
I am still lifting occasionally at the moment, work has me extremely busy. When I do lift, it doesn't really bother me other than I seem to have lost flexibility in my hips. I believe my body is protecting itself because although I stretch and work on mobility, something is awry. I also believe the psoas on that side is jacked up as well.
I appreciate the help I have been given so far.
