Hi there!

The swelling, warmth and the discomfort/ pain following a surgery is most commonly due to the associated inflammation and is likely to subside in a few days/ weeks. However sudden increase in pain or swelling could indicate other issues such as infections, degeneration, injuries etc. I would suggest having this evaluated by your treating doctor for an accurate diagnosis and appropriate management, if required.
Hope this helps.

Take care!
