I went through something almost identical to this, about 6 weeks before a marathon. Coach is definitely right, don't try to run through it, it doesn't help. One thing you didn't mention, however, was any strength exercises. My Dr. said most of the issues he sees in this area are lack of strength in the Gluteus Medius area, and had me doing the following exercises daily, along with water running (which is boring, but works).
1) Standing Sideways leg extension with elastic band. To do this for your right leg, balance with your right foot barely off the ground, and an elastic band around your right ankle and anchored to something sturdy to your left. Extend your right leg out to the side, against the resistance of the band.
2) Side-lying leg lifts. No resistance other than gravity, but if your hips/glutes are weak like mine were, 20-30 of these will wear you out
3) Side-lying "clam" with elastic band around the knees
4) "Fire Hydrants" (Google fire hydrant exercise)
5) "Lateral Band Walk" (again, Google is good. I do this with the band around my ankles, not my knees)
Good luck!
