Running sores are a type of wound or ulcer that continually discharges pus, blood and/or other bodily fluids. Some common synonyms for running sore include open sore, weeping sore, oozing wound, draining ulcer and suppurating lesion. These terms describe the same condition and are often used interchangeably by healthcare professionals. In addition, some may also use the terms infected sore or chronic ulcer to describe a persistent or recurring running sore. It is important to seek medical attention for any running sore to ensure proper treatment and prevent potential complications such as infection or tissue damage.
