Hi, I had gone through your question and understand your concerns.
First of all don't worry much.Focus on the treatment as prescribed.
You didn't mentioned the grade of the
sprain.
I will suggest you fast relieving therapies-called as RICE i.e. rest,ice,compression,elevation.
Rest yourself,use crutches, apply ice to the injured area as soon as you can to reduce swelling,first day, you should apply ice every 20 to 30 minutes, three to four times per day,later apply every three to four hours for the next two days.Elastic compression wrap,first 24 to 36 hours.Raise your ankle above the level of your heart for 2 to 3 hours a day if possible.This helps to reduce swelling and bruising.Taping is also a very useful technique, you can even dance along with it after a little improvement.
Ibuprofen or
naproxen can be used to reduce pain and swelling.
You can also go for
physiotherapy sessions.
