She's a physiotherapist specialising in lymphoedema and oncology related therapy. I can PM you with details if you are in Melbourne or she may be able to recommend someone elsewhere else. Disappearing on its own is great, but I found out the hard way that it's not just inconvenient if a seroma hangs around (mine just refilled when aspirated) but it's a potent incubator for infection. With hindsight my first infection started long before any aspiration, although that too is a bit of a risk. Anything that encourages natural dispersal is worth a shot. As my therapist says, there is no proven link between a seroma and lymphoedema, but it's hard to let the water out when the plug's still in the sink! Good luck.
