Hello and Happy Monday, BarabooProud
The area is also very hot.
Typically you will notice a temperature difference between your surgical and non-surgical knee. You will experience
warmth in the knee due to the healing and increased blood flow to the area. However, intense or increasing heat should be addressed especially if there is increased redness or swelling, fever or chills, wound drainage or significant pain that's worsening.
I hope you get the pain under control soon. Lots of comfort to you!
