A couple weeks ago, when I was taking my son to his mom's, I had a sudden bout of red little bumps show up on both arms (mostly tricep and elbow area), back of my neck, and my back (I could feel it there). They were incredibly itchy.
I have no known allergies, but my gut instinct is I had an allergic reaction to something, as this was two weeks after I had stopped drinking. My son freaked out and took pictures. I told him, as long as my throat doesn't start to get swollen, all is fine and that daddy was just turning into a lizard
But aside from that day, no itchy skin and not yellow.
