I am Dr. Thomas, a double board certified US doctor. You can save time and avoid delays by requesting me specifically in the medical category. Use a long request lock and "for Dr. Thomas only" in the question title.
This is a potentially serious situation.
This situation needs a post operative examination first, before doing anything else.
It can be infection. You do not have to have red streaks or discharge. That is a myth.
And a lot of swelling and heat is indicative of infection.
Which could be serious if not attended to. In fact, the operation can be for naught if you wind up with infectious joint damage.
Go to the ER; have them look at it; have them call your doctors group.
See if it needs to be sampled for the lab.
To answer your initial question, you should not increase activity, you should rest and elevate the leg until you are seen. Icing is fine.
OK, so that is an initial answer….
