I'm a ER Nurse and I done seen almost everything that came to the ER from gunshot, lacerations etc. I also respond to trauma alerts when we have one. But I never in my life seen or heard of leech therapy. I was visiting my a friend on the Trauma/Surgery unit on my lunch break when so I entered the room the patient had like 5 leeches sucking on his hand I could of threw up & I never was the type to get the creeps when I seen stuff in the hospital. have any nurses perform or saw Leech Therapy.
