i'm a runner and lately i've been running on pavement. about a week ago, i noticed a sharp pain on my left hip. it only lasted for the first 5 minutes or so of my 30 minute run. it only lasts for that short amount of time..it never hurts otherwise. could it be a stress fracture from running on the concrete?
I doubt seriously it's a fracture. It would hurt more and for longer. Maybe drop intensity a little until the pain is gone and make sure you have good shoes. I had a pair that hurt my hips, knees and ankles. It makes a big difference, especially when running on pavement.
