I discovered that the worst part about the wound vacuum is that when you change it, the hair around the wound comes with it. Whether or not you want it to.
Fact: Wound vacuums work. It's still the same size, but the swelling and edema around the wound is gone. The part of the wound where the cave used to be is surprisingly healing first.
Just last week, this hole looked like this.
Two to three more weeks.
