I've badly sprained my ankle 3x since april. why does this keep happening and what can i do to prevent future sprains?

See: See your doctor, you may need some out patient therapy to strengthen the muscles around your ankle to help prevent this type of injury.

Need imaging: Sometimes extra bones in the foot or ankle can predispose you to ankle sprains. At minimum an x-ray should be done if not an MRI to rule out these anomalies. After this, an appointment with a foot/ankle specialist may be necessary.

Physical therapy: One thing that can help prevent future sprains is physical therapy, which not only helps strengthen you muscles, but also improves your balance so you are less likely to have your ankle twist. You may also want to invest in an ankle splint from your local sports store to give support to your ankle until it is strong, not just pain free. Also look into your shoes - do you wear heels?

Lax joint: If you you did not immobilize joint long enough, sprain might not have healed well. Seek a second orthopedist.Dr m.

Physical therapy: You need to strengthen the ankle to prevent further injury to the ankle.

Ankle Instability: Lateral ankle instability is a common problem seen in our practice. If you continue to sprain your ankle, the ligaments could be stretched or torn to the degree that they are no longer keeping your ankle stable. Physical therapy using a baps board may help to retrain or strengthen the ankle ligaments. An ankle brace should be used to control ankle motion. Surgery may be necessary to stabilize.
