Doctor to examine: Rashes and spots are difficult to describe in words. Generalized spots that don't itch may be part of an infection (some viruses cause this). "Generalized" means the rash is all over the body. Itchy spots may be an allergy to something. Bluish or purplish spots may be blood spots and may need blood testing. Sometimes, rashes have unknown causes. One's doctor can examine in-person or via video.
