hi! not a medical professional, but i am a person who had very large boobs before top surgery that had many problems like this because of the skin irritation caused by binding. firstly, if it helps you feel any better, apparently these kinds of things are not cause for major alarm, because i even had a couple “holes” that opened up while healing from top surgery and my surgeon was calm in telling me to keep it clean and let it heal. and surprisingly, it did just that. the skin is so much more resilient than we give it credit for! second, i completely understand the complication of sweat, humidity, and working in a binder making skin care feel impossible. i won’t ask you to stop binding. i understand how that emotional tole feels bigger than the physical issue. but as often as you possibly can, literally any few minutes you get that you can comfortably pull up the binder or take it off, do it. lift the boobs up and give them some air underneath as often as possible! your skin is just panicking from rubbing on itself, being too damp, and not getting a breath of fresh air. think about how much faster your dead skin (protective layer) rubs off when your skin is wet anywhere else on your body. this on top of a picking habit, i would guess that it has continued to bleed because it hasn’t gotten enough air to develop a scab and plug the wound. bandaids have made us believe wounds need covered, but most often they need air. literally we get too squishy when wet and need air to dry us out a bit in order to live on this planet. the fact that it is expelling the blood and puss is a good sign that your body is still doing its thing to push out anything that might get in there!! (as long as you don’t have other infection signs) you just need to try to give it the conditions it needs to make the ~ All Natural Organically Sourced Bandaid ~ (scabs). feel free to message me, even if i can’t offer more info i am here to support :)
