Should be examined: Rashes are difficult to describe in words. Spots may be an eczema rash, allergic reaction (usually itchy), irritant or chemical reaction (work chemicals, cosmetics,...), infection (tinea, ringworm,...), or a disorder under the skin. One's primary care doctor can take a look in-person. Maybe an online consultation (like our premium service) with good video can suffice. Ask for Talk To Doctor.
