buy tegaderm rolls off amazon for the next go round. much cheaper that at a local CVS or whatever.
they also sell gauze that's soaked in petroleum jelly that works beneath regular gauze as a good makeshift for places tegaderm doesn't like to stick.
how do you make your wound moist/not dry? do you just pour water on it?
Use your favorite antibiotic ointment, keep it covered.
Demain, on roule!
