my wound is about 1 inch and smells horrible. it started just swelling and then i put icthammol on it thinking it was a boil. I have had those before and wanted to draw out infection. Well next day under skin i noticed like a blood dot about half inch round and then the next day it was a hole about an inch and then it turned black on edges which now that is gone and it has greenish yellow in it but only leaks clear smelly liquid?
