Cholinergic ?: There is a condition known as cholinergic urticaria (small bumps) which occurs during the cooling down period after a rise in core body temperature (hot shower, exercise, stress etc). If this fits your pattern, then try taking the antihistamine up to every 8 hrs to see if this may work.
