Even though I know I shouldn't, I scratched open a wound in my face each time, but now it doesn't heal. When I scratch it now, a lot of clear fluid comes out and when I let it be there comes a crust on it that doesn't seem normal and doesn't look nice. Could it be that it is infected? If so what do I do and what is the fastest way to let it heal? Last of all, I have Calendulan here, could that help?
