Respected sir, I have understood your concern, I know you are passing through tough time. see as you mentioned, you had injury previously so due that, muscles of whole body may weak, or you have neglected to do so called physical therapy properly. now ankle joint which is less stable outside than inside, so due to recurrent injury to ankle joint makes outer ligament weaken, so subsequently chances are higher to reinjury, if we do strengthen muscles surrounding ankle joint properly. you need to take physiotherapy treatment for 1 month, use stability tools like boot to prevent ankle twist again. see to that you don t walk on uneven terrain. I hope satisfied with this answer.
