I've broken two ankles and had them both seen to by specialists.
The ankle and wrist joints are particularly complicated, and with the weight ankles take you don't want to risk it healing without proper management.
Don't waste time on the internet, get it seen to by medical specialists or you'll risk limping for time to come.
ok, with the amount of bruising you have and swelling you have definitely torn some ligaments or soft tissue of some kind, could even be a syndismosis tear, ligament between two lower leg bones, either way sounds like a grade 2 or even 3 tear with that uch colour and swelling and pain. thats the start, it is possible to have fractures that are not complete and still walk etc. could even be worse again. problem is you dont know? how do you? get an xray quick as. but first thing is first 48 hours bucket of ice water to reduce swelling plus yes elevation, no alcohole or anti inflamatories as they cause more bleeding and make swelling worse. yes these soft tissue injuries can end up being way worse than fractures, i had bad damage to my knee, surgeon said i would have been better off with a break. importantly ed will tell you how bad straight up, but you need to to see a musculoskeletal speacialist, either sports physio, sports physician or orthopedic surgeon asap, as this is their bread and butter.
You need to be moon booted asap, and non weight bearing to reduce any possibility of long term damage. these above dudes will get you into a moon boot asap, hire or buy crutches from a chemist now, dont put weight on it till then. Dont trust A& E or ED as tey get it wrong sometimes.
so Ice, non weight bare, crutches, moon boot, specialist physio,dr or ortho asap, they will order xrays or mri, which ever you can get into first. Dont fuck around and be a hero or you may pay for it in many ways.
