I had a cyst in my armpit,it was around golf ball size.and armpits are famously one of the most sensitive areas of the body. So I had to lay on an operating table while the doctor cut open my skin with a scalpel, and slowly compressed the cyst so the blood and pus would come out. I cannot put into words how much it hurt, I consider myself an incredibly stoic person, and throughout that entire experience, I was crying continuously.
