Stress fractures heal with time and rest. Athletes are advised to rest from any activity that caused the stress fracture for the 6-14 weeks that the fractures take to heal (ask your doctor how long your particular fracture will probably take to heal), or until pain-free for 2-3 weeks.
If the fracture is not severe, the healing time will take 3 to 6 weeks, provided that you rest. There is no magic way of getting a bone to heal, because the body will heal it on its own in due time. In the meantime, take it easy and get some rest.
