Possible venous issu: If the swelling progresses as day does and improve in the morning...it could be related to "leaky" veins.

Water retention: It is unusual for a young woman to have such water retention - perhaps because you are on a steroid. Watch for salty foods like soups, pickles, cured meats like ham or salami, olives. Be sure that you get a full evaluation to make sure that your heart and kidneys are healthy.
