In my opinion, you need to actively rehab your ankle and significantly improve the strength in and around the ankle joint. You also need to get in there and break up the scar tissue and improve range of motion. If you have a good rehab pro, then use him/her.

If not, I have found an excellent at home rehab program that I recommend to all my clients. It is called H.E.M. It works quickly and is extremely effective.

I have yet to find anything else that is simple to do and can be done at home without any equipment. It contains a complete rehab and prehab treatment program with a wide variety of healing techniques, stretches and exercises. Give it a shot and let me know what you think.

Best,
Mark
