I have a fistula. Its a big, freaky, bulgy vien on my arm used for dialysis. I need it to stay alive, so sometimes when I'm wrestling with my boyfriend I go "ooh.. fistula.." if I think he's putting too much pressure on it. A friend of his was curious what I was talking about so he googled it. Apperantly, fistula means "to join together" in latin or something. There are at least 2 medical meanings for it. When he googled it he found information on an anal fistula, which is basically when you get a huge sore on your butthole and it HEALS SHUT! Hahaha he thought I had this! He finally noticed when we were wrestling I said that when my boyfriend grabs my arm and we talked about it.
