Thanks for your query
After going through your description, my advice would be rest, ice fomentation and compression bandage along with medicine like ibuprofen
and chymoral forte to reduce pain and swelling. .As you are able to move around with minimal swelling it does not looks to be serious injury.
If you have knee brace
you may wear it for few days, no harm in it.Peroneal nerve injury
leads to foot drop
along with numbness in foot which you do not have. So just relax.
