OK. Seroma are the pits (pardon the pun) I'm going to tag @onemargie for this one as I seem to remember she was using silicone dressings at one point. @primek might have some advice as well.
I know you can buy decent dressings online much cheaper than you can get them at most chemists, which still may not be affordable long term. Thing is, it takes a week or more for them to arrive and, of course, we all hope the problem will have buggered off by then.
I was stuck with a weeping horrible in my armpit post wide excision. A friend subbed me a pack of silver infused dressings. I don't know if it was the dressing or timing, but that wound got all pink and clean very quickly once I started using them.
