Hi last night as I was walking on the street to meet some friends at a bar, I was scratching my leg and moved my head to the side and my head touched or bumped a metal box that contain the power meters for electricity, when I got home I checked and didn't anything but a small red spot in my sideburn, but I also have several of these on my head and use minoxidil for my hair, if there was any fluid like blood would there be a risk for hiv it was like at 930 pm and when I came back to check after I left didn't see any través of blood
