As far as my family goes, it use to be a frequent thing for my grandmother, my mother would get them far and in between, sisters was just about the same. It was just when it hit me, I don't know if it was because of diet or what because younger me, 10-12 me, ate poorly. But the older I got my diet changed (sort of) the introduction of Crohn's Disease caused me to drop about 40lbs over 3 months. The things I use to love all tasted weird lol.
Wound Vac therapy is amazing. It worked for me, as much as it could. My body… is just a special kind of subject. So what they do is cut and place a foam like substance over the wound, not in it. Then there is a film to keep the it down and provide the vacuum. The wound vac is connected to the film and once you cut it on, it starts the suction. It can be a little uncomfortable but trust me when I say, if you have a hole or chronic non-healing wounds, it will bring it up to the surface. From there, you just have to dress it with whatever your doctor recommends. I here silver is still a go-to for some. It's silver something, can't think of it, someone may have to chime to help you with that. But once its level, I don't doubt a good bandage or gauze to do the trick. Thats how flush it'll get it.
To start using wound vac therapy, I had to be referred through a wound care clinic. Some can actually do it there. You have to get it changed every 3 days or so and it will stink. But the end result is worth it. They'll measure the depth every time you visit, which can be uncomfortable. But it works.
Peace and Blessings,
