Tony: hang in there! Those Wound-Vacs can be great, I've seen some remarkable healing with 'em. Also, had a home health pt (who lived in squallor) that had gallbladder surgery abcess. Dr's decided to leave the wound open and have me pack it. I could get most of my hand in the wound starting out. She did finally heal up.
Now would be a good time to make up your mind for some life-style changes (I'm assuming!) like a bit more active, drop a few pounds, watch what you eat, QUIT TOBACCO!! Really, if you use tobacco that's the only drastic change, everything else a little at a time. It's all in your head, man. LOL
Plus, what the others said!
Stay safe.
