The skin on your elbow is called weenus. It is the area of your elbow that covers the olecranon, which is a bone that extends backward from your forearm. The olecranon has a hard surface and is surrounded by skin, which protects it from friction when you bend your elbow or reach across your chest to grab something.
The olecranon is connected to the other two bones in your forearm that form the elbow joint. The elbow joint is a hinged joint made up of three bones, including the humerus, ulna, and radius. The bones are held together by ligaments and a fluid filled sac that surrounds and lubricates the joint. The skin on your elbow helps keep the joint flexible and protects the underlying tissues and bones from injury and infection.
There are several conditions that can affect the skin on your elbow, such as eczema. The skin on your elbow can also become loose over time. In this case, you may need to tighten your skin with a procedure like an elbow lift.
The most common reason to visit the doctor for an elbow problem is to diagnose and treat olecranon bursitis. This is a painful condition that involves inflammation of the olecranon bursa. All big joints in your body have bursae, which act as cushions and shock absorbers between the bones and muscles, tendons, or skin. When a bursa gets inflamed, you may feel pain when you bend your elbow or when you push down on your palm with your finger.
