(HealthDay News) -- A stress fracture is an overuse injury that usually occurs from exercise, such as running.

Fatigued muscles after a while aren't able to absorb the stress of a certain activity, so the bone begins to absorb the impact, resulting in a tiny fracture.

The American Academy of Orthopaedic Surgeons suggests how to help a stress fracture heal:

• Take a break from the exercise or activity that triggered the stress fracture. Generally, healing takes about six to eight weeks.
• If possible, limit yourself to light activity that doesn't cause pain for your particular fracture.
• Using a brace or shoe insert may help speed healing.
• Don't resume the activity too early, as re-injuring the area could cause an even larger, longer-lasting problem.
