I ran 14 miles Saturday morning, felt great, no pain to speak of. Go to the grocery store about 3-4 hours later wearing flip-flops and my foot starts feeling sore. Fast forward another 3 hours and I can hardly put any weight on the foot. Pain is in the outside of my right foot towards the heel. No amount of stretching helps and there is some swelling in the area. Does this sound like a stress fracture? Tia
