    'Deondre' is correct - when you have a cut or other abrasion you have exposed nerves.

    Personally, I love to feel the burn - it lets me know it is working. I use rubbing alcohol almost exclusively on any wounds I get.

    Because it is killing germs that are in the cut.

    The alcohol doesn't physically burn you, but you feel the sensation because the chemical activates the same nerve receptors in your skin that let you know something is hot.
