I had a severe sprain which was a complete tear of my atfl ligament along with damage to the cfl. i'm immobilized but unstable. will stability return?

Ankle sprains: You are describing an ankle sprain with 2 of the 3 ropes that hold your bones together (ligaments) on the outside of ankle torn. (Get xray if bones hurt). For first sprains, most people do well with rest, ice, elevation and gentle range of motion activity. Later, exercises often strengthen the supporting muscles and can help. If the ankle remains unstable make sure to see an orthopaedic surgeon.
