All day, I have had what feels like sharp pin-pricks around my right extremities. The first one I noticed came back in the same area in a few times. It's generally been around my elbow, knee, back of my hand, shoulder and top of my foot. All have been on the right side, except one on my left wrist. I can't think of any drastic changes in my diet, other than Saturday, I did go out drinking for the first time in a few months. I find scratching helps momentarily, however I don't want to scratch too much.
