Elbow bursitis, also known as olecranon bursitis, occurs when the fluid-filled sac (bursa) at the tip of the elbow becomes inflamed. This is often caused by prolonged leaning on hard surfaces, a sudden blow to the elbow, or an underlying infection. The most obvious symptom is a visible swelling at the back of the joint that can look like a small ball or “goose egg,” which may be accompanied by tenderness and redness.
Treatment typically involves protecting the area with elbow pads and avoiding direct pressure on the joint. If the swelling is significant or doesn’t improve with rest, a doctor may use a needle to drain the excess fluid (aspiration). In cases where the bursa is infected, antibiotics are necessary, and in rare, chronic cases, the bursa may need to be surgically removed.
