unfortunately I am on the gold coast @Afraser - but I would appreciate any names of OTs or physios here.
I was speaking to my son, who is a recently qualified OT, who is going to talk to the OTs at his Brisbane clinic who have a lot of patients with post mastectomy swelling/lymphodema. It seems to be recent OT training that endorses massage as an effective treatment for both lymphodema and seroma. He echoes your therapist - the fluid, whether water or lymph, still needs to find a way to drain past compromised/fewer lymph nodes and/or scar tissue. Those OTs might also be able to recommend therapists down my way.
It's very reassuring to hear that lymph drainage was working for you (before the last infection).
@Renatha - did your seroma develop 8 weeks post surgery and are you still having massages?
thank you @Afraser and @Renatha
