Hi... Since there is a fall and significant swelling.. If I were I would have got a x-ray done for my ankle and check.. after getting confirmed that everything is ok...then I would suggest you.. To continue icing frequently for 15 mins once in every 2 hours..make sure your body temperature gets back to normal..before icing the place again.. To wear a ankle support ...or keep it compressed by a compression bandage... keep it elevated... take rest... Numbness and chillness what you experience could be due to swelling even pain while bearing weight can be attributed to the same... Nothing to worry...Things will get alright Hope this is helpful for you... kindly revert back incase you need any further clarification....
