Hi, I had gone through your question and understand your concerns.
You haven't mentioned the age, the exact place of
injury.
A swollen joint is generally more "bark" than "bite" when it comes to injury.
Its a natural healing process but still important to control.
Basic first aidis necessary known"PRICEM", which stands for:
Protection,rest,ice,compression,elevation,medication (eg. anti-inflammatories).
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.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.
Ibuprofen or
naproxen can be used to reduce pain and swelling.
You can also go for
physiotherapy sessions.
