Massage for Reducing Swelling from Seroma?

There is no role for massage in the treatment of a seroma.  This is a collection of fluid under the skin and fat not uncommon after abdominopasty.  Treatment is serial aspiration.  Massage has no role in treatment.

Seromas are collections of fluid under the skin.
Seromas should be drained, and not be allowed to resorb on their own.
If left untreated, seromas can become permanent and form a capsule that needs to be removed surgically.
They can also become infected.
There are various methods of reducing swelling, primarily by reducing activity levels, applying compressing, avoiding prolonged sitting, and lymphatic massage. However these are treatments for surgical swelling, not seroma.
