I have a dermatological question....I recently had sunburn on my forearms. Throughout the day, it was red, sensitive and very warm (typical sunburn symptoms). The next morning I woke up with dozens of small dark circles along my forearms, similar to freckles. I have olive skin, tan quickly and easily and burn infrequently. I'm not sure what they are - they aren't raised bumps, they don't itch or hurt. Could they be sunspots? I'd like to know what they are and if they will fade. Thank you!
