Wait, What?

So I have a staph infection (I think). I had one last November and this painful red lump looks strikingly similar. I was showing it to my mom and Grandma last night and got the appropriate answer of "ewww, poor baby." Then, Grandma says "You need to put bacon on that." Oh okay. Wait, what?! "Yeah, you put a tiny piece of raw bacon on it and it'll help it get better." So I dubiously ask "Just bacon?" Then, my 78 year old sweet-as-honey grandmother ROLLED HER EYES at me and said "Well no darlin', you'll also need a band aid."
