How To Treat Pain Caused Due To Stress Fractures During Sports Regime?

I constantly hurt and get stress fractures once a sports season. I don t think I am depressed, and I am a very active high school athlete. My main sport is running. I have a very healthy diet and consume a significant amount of calcium through milk, cheese, and other dairy products. This has been going on for about three to four years. No doctor can give me a solid answer. What are your thoughts? Thanks.
