A skin sore is an unfamiliar appearance on the skin, which looks like rashes, boils, wounds, swellings or bumps, which take weeks or sometimes months to heal. Typically these sores tend to multiply rapidly or recur. These sores at times may also be accompanied by fever or feeling of nausea.

Skin sores may be caused due to hundreds of reasons which may be difficult to detect. For instance sudden formation of bumps on the face may indicate that it may be HIVES or cold sore or a reaction to medicines.
