You've probably already read this, but...https://patient.info/health/sports-injuries/ankle-injury-sprained-ankle
The bruising usually (but not always) means it's a sprain, not a break. Sometimes the two happen at the same time.
I've got legendarily bad ankles, mostly from numerous bad sprains and breaks in my reckless youth. I've had one minor operation (to remove bone spurs and re-attach a ligament), and am getting cortisone shots every 3-6 months because the injuries have resulted in traumatic arthritis. It sucks. I'll probably have to get an ankle replacement surgery on the left within a year or two. Still, I can strap on my brace and play 18 holes with only a little pain, so I count myself lucky.
I agree with the others, go see an doctor. It's *likely* just a bad sprain (though they're no fun, and you're in for 3-4 weeks at least of pain), but if it is broken and you don't get it taken care of, you can limit your mobility permanently. Go get x-rayed and rule that out!
