Lyme spirochetes have a reputation for causing that to happen to many people.
It will resolve eventually, if you get the Lyme under control to where you have no symptoms of any kind. That is unless real damage was done to your cartilage, etc. An MRI should be able to detect that.
Is this the last symptom you have left? You might need an alternative form of treatment to get the bacteria out of your deeper tissues where abx doesn't reach, and continue treatment for at least 2 months past your last symptom.
ETA: The swelling is likely due to inflammation, bringing in excess fluids. So herbal treatment such as Japanese Knotweed, and other herbs can help deal with inflammation, but you might also benefit from detoxing.
If you haven't already, we want to encourage you to read our first topic "New to LYme?...start here", in there is a section on easy de-tox methods that really help.
