Holding Gauze with forceps, slowley "feed" the wound by pushing with the cotton swab in increments the size of the cotton swabs head. Repeat until wound is filled.
This was my summer vacation last year after being released from the hospital due to a tunneling MRSA infection. I had two wounds like this but initially they connected until tissue had healed some of the gap.
It must have felt so good when he got to the end. Oh man. I want to get hit by an improvised roadside bomb just so I can take the gauze out of the wound later.
