You need another opinion. if you really tore all the ligaments and tendons, I doubt the treatment you were advised is the right treatment. You sound like someone who, like me, hates going to the doctor, but you need to get to a big city and see a specialist.
There are extremely few injuries that are not found in NFL medicine. Ankle injuries of all kinds are treated by team specialists. If you live near Nashville, find out who is the Ortho surgeon for the Titans. Make an appointment. I guarantee they are familiar with your injury and know how to ‘get you back in the game’. They treat multi-million dollar ‘assets’ regularly.
