Ulcer external

Ulcer external is a type of skin lesion that is caused by a break in the skin, leading to an open sore. It usually appears as a red, raised area that is often painful and may have a yellowish or white pus-filled center. The area around the ulcer may be swollen and warm to the touch. Ulcer external can develop gradually over time, or it may appear suddenly. It is often associated with conditions such as diabetes, poor circulation, or an infection. It can also be caused by an injury or friction on the skin. Treatment may include antibiotics, topical medications, wound care, and lifestyle changes.
