I've been through 4 dressing changes on the wound-vac since I started using it June 28th.
Incredible. That's how I'd describe the effect.
In 9 days, the big incision site has closed up to the point where its about as wide as a pencil (compared to about an inch) and about the same length (a little under 2 inches).
There was a smaller one a little larger than a pencil diameter just below this one which used to be connected to the larger one by a "tunnel" where the skin mended while I still had staples there. This one's nearly closed, now.
The redness around the staple spots has gone down noticeably.
Word has it I'll be rid of the thing in another week.
