Did you use the crutches, per coaches advise?
If the pain comes back see a Dr. and get an evaluation using all the tools, 6 month is a long time. Just for your peace of mind.
Here is more. These are my answers to similar Ankle problem edited specially for you.
*************
See a sports specialist Dr. Get a Fibber Glass-Velcro ankle support (removable and adjustable) and use it. or get special shoes made with support.
Dr. should show you few ankle strengthening exercises. Then do them, once you roll an ankle it get week and it may roll more easily next time, I think this is the case with you. You are rolling in your sleep or rolling it slightly without knowing, but the effect is delayed.

In your case ankle problem.
1). Use crutches. Rest. (do not play sports and lift any thing heavy, go to a pharmacy or medical supply and ask for a ankle support, in your case get it and use it all the time but light exercises are OK ).
2). Cold and Hot compressions, alternately(ice the swelling in your case).
3). Pain killers such as Aspirin/Tylenol/ other.
4). Vitamin B6 it help rejuvenate the tissues(available over the counter.
5). Apply pain killer ointment and massage it lightly (to affected joints and mussels).
After healing, do light stretching and slowly get in to usual routing step by step.
Hope you have seen a Dr. and had a X' Rayed taken, or had MRI done (preferably both). Make an appointment for a Dr. and if need be cancel it later in time to avoid visit fees, if you get batter in time.
Treat the scratches with antibacterial. Like Bactine(it does not sting) or Equal, keep it covered and clean
