What ordinary healing looks like, and the signs worth a call.
Warmth and puffiness that ebb and flow with activity are normal for months. Calf pain, fever, or swelling that gets worse for days in a row are not: those earn a same-day call to your care team.
Compare your knee to itself, same time each day. Swollen tonight but calmer by tomorrow evening: fine. Bigger two mornings in a row: scale back and tell your PT.
These actions arrive with appointments and plans.
Guides educate, your care team decides. Bring the questions, not the printout.
