Recently vet said you want the proud flesh to stick up a little because that causes faster skin closure. Who knows.
The definition of proud flesh is granulation tissues that has grown ABOVE the level of the skin and will NOT allow the wound to heal because the skin cannot grow over the top of it.
So no, you do not want the proud flesh to "stick up a little bit". You want the wound even with the skin so that the skin can grow in and heal the wound.
I've never put cortizone on anything quite like this, but I've thought about it. Is it ok to do, or anything to look out for?
Steroids control inflammation but they also inhibit healing, which is why they function well to "knock back" the proud flesh. OTC hydrocortisone is fairly mild so you don't have to be quite as careful with it; but as a result, it doesn't work as fast as some other things, but it does work.
ProudsOff on the other hand is very caustic so you do need to be careful to apply it only where you need it (and nowhere else) and only when you need it, but it works extremely quickly.
Personally, I don't like debriding because it's going to bleed like a stuck pig and the cutting is causing stimulation .... which can make it jump right back to where it was before you debrided. I much prefer to slap some ProudsOff on it and be done with it.
