What Is The Remedy For The Bruising And Swelling In The Ankle?

hi, i injurred my ankle 2 weeks ago doing a stunt in cheerleading, 3 people landed on my ankle while it was rolled and twisted in a weird position, i went to the doctors but he was not very helpfull at all, he looked at it and said its a sprain, but that was before it started bruising and swelling in a couple hours after. it was then hard to walk and now two weeks later it hurts in some movements. it is slightly swollen and its bruised in the same spot on both sides on my ankle i cant stretch my ankle. do you have any ideas that could help ? thankyou.
