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 your hand inflammation is a similar thing - Lupus deciding your hands are foreign bodies 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.
