An ankle sprain is a stretched or torn ligament, and chronic ankle instability is when the ankle keeps rolling or giving way afterward. Most sprains heal with protected movement and rehab. For ligaments that stay sore, Dr. Paul Tortland, DO, may use an ultrasound-guided injection such as prolotherapy or PRP. An ankle that keeps giving way despite rehab may need a surgeon.
