I’ve seen multiples dermatologists about this problem to no avail. Over the past 2-3 years, I’ve been getting these extremely itchy pimples randomly on my forehead and, on rare occasions, other t-zone areas. The areas start out very much like a hive (red, blotchy, extremely itchy skin), but, unlike hives, end up leaving a red papule with the occasional white center that stick around for days to weeks.
