Which doctor can i see about odd looking sores on my body?

One's primary doctor: Rashes can be hard to figure out without looking at them. One's primary care doctor can examine. Little blisters can be viral, bacterial, or contact dermatitis. A rash can also happen sometimes if a person's body is reacting to a germ causing viral or bacterial symptoms (sort of like an allergic reaction). Strep throat bacteria can make a toxin that causes reddish rashes, but not open sores.
