One of my little fingers got on infection along side the nail. Slightly painful, but red and swelling showed the infection. Came to mind about this thread.
THEN.....I remembered a very basic 'drawing' technique for such infections and have been soaking that finger every few hours in a small bowl of hot water with lots of salt in it.
Even this first day, the effect is almost miraculous, and I should think that within 48 hours will be totally healed.
Salt is a wondrous healing compound - best way of treating any minor cut/would or infection.
