Elbow Bursitis (Swollen Elbow Tip): Symptoms, Causes & PT Treatment
Updated July 20261 minute read
Elbow bursitis is swelling of the bursa at the tip of the elbow — often a soft, fluid-filled lump that may not even hurt much. It's commonly from leaning on the elbow, a knock, or repetitive pressure. Most cases settle with avoiding pressure on the elbow and time. The key safety point: a hot, red, very tender bursa with fever can be infected and needs urgent medical care.
What is elbow bursitis?
The olecranon bursa is a thin sac over the bony tip of the elbow. When irritated, it fills with fluid and swells.
Symptoms
The classic feature is a swollen, sometimes squishy lump at the tip of the elbow. It may be painless or mildly tender; pain is more pronounced when leaning on it or fully bending the elbow.
What causes it / risk factors
Repeated leaning or pressure on the elbow, a direct knock, repetitive friction, and sometimes underlying conditions like gout. Infection is an important cause to rule out.
How it's diagnosed
Diagnosis is clinical. If infection is suspected (hot, red, fever), medical evaluation — sometimes fluid testing — is needed.
Physical therapy treatment
What a PT does. For non-infected bursitis, your therapist helps offload pressure, restore comfortable motion, and address contributing habits. Exercises & progression (overview). Pressure avoidance (elbow pads, not leaning), gentle motion, and gradual return to activity. Recovery timeline. Many non-infected cases settle over a few weeks once pressure is removed.
Treatment options compared
Pressure avoidance and time are first-line for non-infected bursitis. Aspiration or other medical treatment is used for large or persistent swelling; infected bursitis needs antibiotics and medical care.
Red flags
A hot, red, very tender bursa with fever (possible infection) needs urgent medical care. Significant injury or inability to move the elbow also warrants prompt evaluation.
