Yep, refilled constanty. Your body is trying to help you by pushing nutrient rich fluid to the site and overdoing it. Conventional wisdom is that to disperse naturally is best, rather than to risk introducing infection by aspiration but as you already
have bacteria in your system naturally infection can occur anyway.
I didn't have to pay for aspiration( was covered by my insurance)but my observation was that draining only led to refilling.
I finally got my lympohoedema therapist to massage the seroma which was gradually working well but I got hit by a very bad infection ( bacteria in the seroma soup) ended up in hospital and surgery. That fixed it once and for all
but 12 months start to end. My first aspiration drew one ad a half litres. It can get a bit crazy.
I suggest you give it another go, but if it just fills up and is uncomfortable again you may want to discuss massage with your
surgeon. You need a trained therapist though.And yes, it may cost but see what's possible through your hospital.
Best wishes.
