Abrasion
An abrasion is an open wound caused by too much skin friction or direct contact with a rough surface. It is sometimes referred to as a scrape, grazes, or road rash. They are commonly found in the knees, elbows, ankles, shins, and upper extremities. Since they are widespread, especially among kids, most people do not give these wounds enough medical attention.
Unlike other open wounds, abrasions are not excessively bleed but can be very painful. This is due to the exposure of the nerve endings found underneath the skin. The severity may be categorized into three grades. The first one is the first-degree abrasion, which involves slight damage to the epidermis. Next is second-degree abrasion, which can affect the epidermis and dermis. It may also bleed lightly. The last one is severe abrasion or also known as third-degree abrasion. This type of abrasion may bleed heavily.
All of these degrees of abrasion may cause necrotizing fasciitis. This is due to the opening of the epidermis, which allows the bacteria to enter and spread quickly. In addition, there are cases wherein the abrasion may heal quickly, but without proper treatment, it may worsen the necrotizing fasciitis. Some severe symptoms due to abrasion are unhealing wounds, irritated skin, and fever.
