Sprain ankes can come from a weakness in your ankle and be an on going problem if not strengthened to prevent it from happening.
Make sure to talk with your doctor and have your ankle looked at before starting a workout program. A sprain ankle is a stretching and or tearing of ligaments. The most common sprained ankle is to the talo-fibula ligament. If the sprain is worse there might also damage to the calcanao-fibula ligament which is further back towards the back of the heel. In addition to the ligament damage there may also be damage to tendons, bone and other joint tissues. It is again important to have your ankle looked at by a doctor.
Taping your injured ankle during the rehabilitation phase to protect the joint without risking further injury. When you are doing weight bearing exercises it is very imporatant to tape your ankle to protect the lateral ligaments while ensuring forwards and backwards motion is allowed keeping the rest of the joint healthy. When stretching your ankle you don’t need to tape.
Rehabilitation exercises are critical to ensure that the ankle heals completely. Crutches may be needed if you can bear some weight on the ankle without too much pain that is a good sign. Start by moving your ankle in range of motion exercise within the first 72 hours after your injury. Make sure to also stretch and strengthen with balance exercises.
