Doctor can check: Rashes and spots are difficult to describe in words. Generalized spots may be part of an allergic reaction or an infection. "Generalized" means the rash is all over the body. Bluish or purplish spot may be blood spots and may need blood testing. Sometimes, spots have unknown causes. A primary care doctor or dermatologist can examine both the rash and the patient, to find a treatment.
