yesterday I had the edge of a toenail removed and cauterized because it was ingrowing, the main aftercare is to soak in epsom salts 3 times a day.
I've never used epsom salts before, I vaguely understand they work against infection, but is the point for it to heal 'open'.
also soak your feet for 20 minutes 3 times a day, great advice, wholly impractical
