Being an orthopedic surgeon, didn’t they tell you that the ankle should at least need a brace, like an “Air Cast-Brace”
after the swelling is gone.
Normally you immobilize the ankle immediately with a tape or, in a severe case like yours, with a cast for 5-7 days
and then, after removing the immobilization, you should wear the brace for 6 weeks.
Partially weight bearing should be allowed after the first days of immobilization and kept for 4 weeks.
Keep the leg up and put ice on it.
I know how you feel buddy! I ruptured my achilles tendon 3 weeks ago at a basketball tournament, 2 days before I was supposed to take the family on holiday. The holiday was cancelled and I’ve been told no driving for 10 - 12 weeks. Knowing our luck it will be an amazing Indian summer with us stuck on crutches lol
They told me to elevate and rest for 2 days and ice packs every 4hrs for the first 24hrs.
Use crutches for 2-3 weeks with occasional resting.
Be careful the next 6 weeks.
Brace was advised as i did the same thing a few years ago on the same ankle (which needed physio).
