What are sores?
A sore is a blister, bump, lesion or ulcer occurring anywhere on the body. The sore may be painful, itchy, red, swollen, or tender to the touch. The sore may be hard or filled with fluid. The surface of the sore may be broken and bleeding. Some sores may not be associated with pain.
There are numerous causes of sores, which range from mild to serious. Sores may occur as the result of a single incident or recur frequently. The type and severity of the sore varies with the underlying cause.
The herpes simplex virus is a common cause of recurrent sores on the mouth, fingers or genitals. The resulting sores on your mouth and lips are commonly called cold sores or fever blisters. Extended bed rest or use of a wheelchair may cause pressure sores. These sores develop due to limited blood flow to the part of the body that is always under pressure from the bed or chair.
Other common causes of sores include allergic reactions, insect bites, eczema, and infections such as chickenpox. Injury may also result in sores. Sores may also occur as a symptom of an underlying disease or serious condition, such as diabetes, leukemia or skin cancer.
Sores are rarely associated with a medical emergency. However, sores may be a symptom of a serious condition such as an infection. Seek immediate medical care (call 911) if you, or someone you are with, experience sores with other signs of infection, such as high fever (higher than 101 degrees Fahrenheit). In rare cases, infections can spread throughout the body, resulting in shock and organ failure.
If your sores are persistent or cause you concern, seek prompt medical care.
