PS thinks stitch got infected 2 weeks post op after he cut stitch out it left a large wound that he told me to clean with betdine (which slows down healing process) I work at hospital so coworkers debrieded wound and we dressed with mesalt which healed the tunneling tracks and wound bed looked better. Then PS last week decided to silver nitrate it and things went bad again it started oozing green stuff. coworkers and I talked to wound care dr and he suggested Maxsorb AG seems to be good job.
