The overactive immune system in Lupus often find strange places in the body to attack! I used to get swollen toes for no good reason - my Drs said it was just where my Lupus chose to attack that day.
Sounds like you ankle/leg/foot inflammation is a similar thing - Lupus deciding your leg is a foreign body that need to be attacked!
You might need to talk with your Dr if this continues much longer - generally a small dose of prednisone for a week or two will help knock out the inflammation.
(Sorry your Dr is doesn't seem to be aware that Lupus can do random things like this -- if the Dr is resistant ask for your inflammation markers to be checked, they should show something is going on. Only sometimes they don't!)
