I had staph infection on my leg, got a surgical syringe(SP? LOL) and cut my leg open with no pain medication to let all the puss and infection out. Needless to say we couldnt get it all out so I had to go to the hospital and get them to numb it and push as hard as they could, it shot up out of my leg like a volcano. When the doctor did it, it didnt hurt. But when my dads friend cut it open, it was the worst pain Ive ever felt
