Olecranon Bursitis: Causes, Symptoms, and UK Treatment Options

Olecranon bursitis is a condition characterised by swelling, redness, and pain at the tip of the elbow. The olecranon is the bony point of the ulna (one of the forearm bones), and the bursa is a thin, fluid-filled sac that sits between the bone and the skin. In its healthy state, the bursa acts as a cushion, allowing the skin to slide smoothly over the bone.

When this sac becomes inflamed, it fills with excess fluid, resulting in a visible lump that often resembles a small balloon or a golf ball attached to the elbow. In the UK, this is frequently referred to as 'student’s elbow', 'miner’s elbow', or 'plumber’s elbow', reflecting how prolonged leaning on hard surfaces can trigger the condition. While usually harmless, it can become uncomfortable and, in some cases, infected (septic bursitis).

Pressure and Trauma

The most frequent cause is repetitive pressure. NICE guidance notes that individuals who frequently lean on their elbows while studying, typing, or performing manual labour are at higher risk. A sudden blow to the elbow, such as a fall or a sports injury, can also cause the bursa to bleed or become inflamed.

Infection

A break in the skin near the elbow—even a small scratch or insect bite—can allow bacteria (often Staphylococcus aureus) to enter the bursa. This leads to septic bursitis, which requires urgent medical attention.

Underlying Conditions

Certain inflammatory conditions can increase the likelihood of developing bursitis. According to NHS records, patients with gout, rheumatoid arthritis, or those with weakened immune systems are more prone to recurrent episodes of joint-related bursitis.

The symptoms of olecranon bursitis can vary depending on whether the bursa is infected or simply inflamed. Typical features include:

• Swelling: This is usually the first sign. You may notice a soft lump at the very tip of your elbow.
• Pain: While some swelling is painless, many people experience a dull ache, particularly when bending or straightening the arm.
• Redness and Warmth: If the skin feels hot to the touch or looks noticeably red, this may indicate inflammatory or septic bursitis.
• Restricted Movement: Extreme swelling can make it difficult to fully flex or extend the elbow joint.

If the swelling is mild and there are no signs of infection, most UK GPs recommend conservative management following the RICE principles:

• Rest: Avoid leaning on the affected elbow or activities that irritate the joint.
• Ice: Apply a cold pack (wrapped in a towel) to the elbow for 15-20 minutes several times a day to reduce inflammation.
• Compression: A tubular bandage or elbow support can help control the swelling.
• Elevation: Keeping the elbow raised above the level of the heart can assist in fluid drainage.

Over-the-counter medications such as paracetamol or ibuprofen can help manage pain. Always consult a pharmacist or check the patient information leaflet before starting new medications to ensure they are suitable for you.

If you are unsure whether your elbow swelling is serious, you can speak to a GP online for a clinical assessment. This is particularly useful if the swelling does not improve after a week of self-care. An online doctor can:

• Review your symptoms and the appearance of the elbow via video consultation.
• Provide advice on effective pain relief and anti-inflammatory treatments.
• Assess the risk of infection and provide a private prescription for antibiotics if required.
• Discuss whether you require a referral to a specialist or for physical therapy.
• Advise on the necessity of a fit note if the condition affects your ability to perform manual work.

Online GP services offer a convenient way to get expert advice without the wait times typically associated with local practices, especially for musculoskeletal issues that are non-emergencies.

Aspiration

If the swelling is particularly large or uncomfortable, a doctor may use a needle and syringe to drain the fluid (aspiration). This often provides immediate relief. The fluid may be sent to a laboratory to check for infection or gout crystals.

Corticosteroid Injections

For chronic or non-infected bursitis that hasn't responded to other treatments, a steroid injection may be considered to reduce inflammation. This is usually performed after the fluid has been drained.

Surgery (Bursectomy)

In rare, persistent cases where bursitis recurs frequently or the bursa remains thickened and painful, surgical removal of the bursa may be recommended. This is a day-case procedure usually sorted through the NHS or private orthopaedic channels.
