This is a dermatological question.
I see this condition more when it starts getting colder outside. During and after taking a shower I get blotchy red patches on my hips and minimally on my glutes. They can be as small as an inch or so in diameter, but on one of my hips I've seen it get as big as about 3 inches in diameter. They are not raised, there are no bumps or itchiness, but the skin has the color of an intense sunburn.
After 20-30 minutes the patches go away.
One more thing, I was diagnosed with keratosis pilaris on the backs of my upper arms and on the front of my thighs, but lately I've been seeing similar bumps (they aren't bumpy as much as small red dots under the skin) just below my knees on my calves and I'm wondering if I might've been misdiagnosed?
Thanks for your time.

I assure you clinical diagnoses from dermatologists can vary from each unless some kind of pathological diagnosis is established (like by skin biopsy). The following list might help better understand the possibilities; although, the dermatologist is the best person to determine the exact cause.
Causes of whealing from Cold Exposure
Cold-induced (reflex) cholinergic urticaria:
Familial (essential) cold urticaria
Cold agglutinin disease
Paroxysmal cold hemoglobinuria
Hope this helps.
