Hello, Thanks for writing to us, I have studied your case with diligence. As per your history and injury pattern there can be persistent tear in ankle ligament leading to pain and swelling. Instability may increase due to laxity of ligament. I will advise to repeat MRI ankle for soft tissue involvement. Till time you can continue use supportive splint or brace. Physiotherapy like ultrasound and TENS will help in early healing. Persistent pain after ankle injury is common and may take 6 months to heal. If there is complete ligament tear on lateral aspect then arthroscopic ankle ligament repair can be done. Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries. Wishing you good health. Take care.
