What could cause my elbow to hurt when I lean on it?

Reviewed by Yoshinori Abe, MD

Internal Medicine

Elbow pain when leaning is most often caused by olecranon bursitis, an inflammation of the small, fluid-filled sac (bursa) that cushions the tip of the elbow. Other common causes include tendonitis, nerve compression, or soft tissue irritation from repetitive pressure or minor injury.

Key causes of elbow pain when leaning:

Olecranon bursitis: Swelling of the bursa at the elbow tip
Tendonitis: Inflammation of tendons from overuse
Nerve irritation: Pressure on the ulnar nerve
Soft tissue injury: Bruising or strain from repeated leaning

Because these conditions share overlapping symptoms but require different treatments, identifying the exact cause matters. A quick, free symptom check can help you understand your specific symptoms, evaluate possible causes, and decide whether home care or a doctor's visit is the right next step—all in just a few minutes, online, and at no cost.

Explanation

A bursa is a small fluid-filled sac that cushions your elbow and reduces friction between bones. When you lean on your elbow, the olecranon bursa—located at the tip of your elbow—can become swollen and irritated. This painful condition, called olecranon bursitis, makes the area tender when pressure is applied. Elbow pain can also result from strained muscles or tendons near the joint due to overuse injuries. Frequently leaning on your elbow or experiencing an injury can cause repetitive pressure damage to the soft tissues, resulting in pain and swelling. To avoid further irritation, avoid putting weight on your elbow. If the pain persists, use our free symptom checker to help identify what might be causing your discomfort and determine whether you should consult a doctor for evaluation and treatment.
