That is great to hear!!! I still have a hard mass, lumps and abscesses. My skin does get dry often and peels but mine, and yours too, is probably just dead skin. After all it's gone through, the skin dies, we get new skin often anyway right?
I think you should still use the gauze if its open and oozing. With wounds, of any kind, I always hear that it's good to keep it clean and dry.
