3 months at severe stage you would just start to notice a difference. I would have warned about yeast but you say there is less disharge. It can get itchy when swelling is going down. If thats the case it just started working.

The kind that is tinged green, if it has any odor than that of fresh hamburger. Bloody discharge can be concerning because it will increase bacteria growth but it also occurs when fighting or healing.
There is an anime on cell productions and healing. I highly recommend it. Its wrote for kids using advanced science. Its very accurate even though the cells are humans. I was impressed and I have been learning this stuff for 15 years now.
There is a reason why wound care has its own department and regular doctors on average know very little about it.
The yellow stuff that doctor was calling puss is the same healing fluid that makes scabs.
Puss is white, creamy, or snotty green and looks like because it is exactly like snot from your nose.

Thank you for that Brook. What colour puss is the dangerous kind?

Well first wounds will always have a discharge. That yellow stuff is not puss. Its actually the healing fluid. If it changes color thats the stuff you worry about because what helps make you heal and grow also grows bacteria. So any doctor telling you they want to make that go away, needs to be fired.

Dermatology was somewhat positive yesterday, (thought it was the end of the month) She's been told that the treatment is going to be doubled up. We will have to wait and see how she responds to a double-whammy treatment. The ideal end result would be for the puss to dry up - colorectal surgery and then plastic surgery to reconstruct the areas where mass has been removed. Feeling hopeful now, thank you for your comment Brook. How is your HS journey?
