yeah the biggest concern is infection… and this doesn’t look like infection to me. if it’s not red, painful, or hot to the tough it’s probably not infected… a light pressure bandage or wrap around it and elevating it above your heart / head for as long as you can each day should drastically reduce fluid retention in 24-48 hours time… but if there is any sign of infection or you have any doubts, then definitely go see the doc.
also don’t lance it.
