I also did my ankle in and spoke to a doctor mate who basically said that you get three different types of ankle injuries:
First - heels in 2 - 4 weeks. It's just a strain on the ankle from being pushed off in the wrong direction
Second - heels in up to 6 weeks. It's also basically muscular and is a grade up on the first one. A bit worse, strain on the ligaments is a bit more. Pain is a bit more intense.
Third - is different because instead of just spraining the ligaments, you actually tear them. This takes a LONG time to heel. And the more you play around on it and stop it from heeling, the weaker the ankle heels. This means that while you will already have a large amount of weakness in the ankle from now on, if you don't let it heel, it may never heel properly and you will have weakness in that ankle beyond.
How do you know you have torn your ligaments instead of just spraining it? It takes AGES to heal. In a nutshell
Buy a wobble board, do some movement exercises and do small ankle strengthening exercises BEFORE going for a run. Right now, it's about helping your ankle to heel stronger, instead of leaving it or running on it and weakening it.
A weak ankle results in more sprains that just get worse and worse
