I itch all over and this morning I had red with white bumps on my neck and now a couple on my elbow! What could this bed?

Possible hives. Hives or urticaria is a red itchy raised rash that can affect any part of the body. In the middle of the hive, the area can appear white from edema. When pressed on, the rash will blanch. As for most rashes, the diagnosis is most easily made when the physician can see it. Because hives can come and go, take a picture of the rash and see your doctor.
