I didn't have an encapsulated seroma but I had a very large one, lasted 12 months, developed a seroma within the seroma and required surgery to finally clear our (after a severe infection). They are a thorough pain, largely caused by your body going into overdrive to heal and, annoying as it may be, giving it time to disperse is the standard response. I found massage helped a lot but got onto it a bit too late to stop (another) infection. My surgeon was very honest about the dilemma - treat with heavy duty antibiotics, which was done and still risk a recurrence or go to surgery with its own risk of infection. Surgery turned out to be the right answer for me - no seroma, no return of fluid, no more infections - but a second opinion is always worthwhile and I had no reconstruction to think about. Can't help with a surgeon as I am in Melbourne but best wishes, it will be good to have all this behind you, whatever course of action you decide on.
