I had a subaceous cyst removed a few years ago .
The doctor told me to get in the shower three times a day , and let the stream flush the wound for a few minutes each time , using a sterilizing hand soap ( Lysol , I think ) . And not to cover it with a bandage – to get air to it . He said the hole would fill in . I laughed to myself when he said that .
He was right and I was amazed !
