Stress fracture?

I had stress fractures in both my legs two years ago. the right one healed, but i still have pain in my left leg (which was the worst out of hte two). i can still push on my leg and pinpoint hte place where it hurts, but some of the other symptoms of stress fractures are no longer there. since its been two years i dont know what's wrong with it...it has just never fully healed. is there such a thing as chronic stress fractures, or does anyone have a clue as to what it could be?
