It started more than 2weeks ago and still present.waking up with red circular small rashes on any part of body ,very itchy. It appears also all of a sudden while awake. Feeling itchy then it appears at that place. It appears as multiple and scattered . it goes after couple of days but appear at a different place of body . I wonder if this is contagious because it happened to me and my sisters. But not to other people at same house .
