I am experiencing skin sores and rash (quality: blisters) .

Doctor can examine: Rashes can be hard to figure out without looking at them. 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. Allergy to certain foods or other substances can create rashes.

More info needed: It isn't possible to judge the cause or possible treatment without more information. Where on your body? How long have you had the problem? Has it happened before? If this is in the genital area or on the face, maybe herpes. Another kind of herpes (herpes zoster, shingles) is possible if it's a localized rash elsewhere on the body. Serious allergic reaction if it's all over. See a doctor soon.
