Olecranon bursitis — causes, symptoms, and when to seek urgent medical attention for infection.

What you're feeling

You will likely notice a swollen, soft lump right at the tip of your elbow. This swelling can happen suddenly or grow slowly over time. You might feel pain when you lean on your elbow or press against it. Many people find that resting their arm on a hard surface makes the discomfort worse.

Daily tasks can become difficult as the swelling increases. You may struggle to reach behind your back to fasten a bra or tuck in your shirt. Lifting objects or pushing up from a chair can also feel uncomfortable. Some patients report that the pain wakes them up at night, especially if they sleep on their side.

If the swelling does not go away on its own, your surgeon may look for other causes. A swollen bursa that lasts a long time could be due to a rare infection or a condition called wear-and-tear arthritis. In some cases, the skin over the lump may look red or ulcerated. If you have had this problem before and it keeps coming back, your surgeon will check for these unusual causes.

What's actually happening

Your elbow has a small, fluid-filled sac called a bursa that acts like a cushion between your skin and the bone at the tip of your arm. Sometimes this sac gets swollen and irritated. This can happen after a bump, from leaning on your elbow too much, or from an infection. If you have a swollen bursa that lasts a long time, it might be caused by a specific type of bacteria that needs special attention.

When this sac becomes inflamed, it fills with extra fluid. This creates a lump at the back of your elbow that can feel tight or painful. In some cases, the body grows extra bone in the soft tissue around the joint, which can limit how well you can move your arm. If this extra bone is removed early, you are more likely to get your full range of motion back compared to waiting.

Your surgeon will look closely at how this swelling affects your daily life. If the fluid keeps coming back or does not get better with rest, they may suggest draining it or removing the sac entirely. Most people who have the fluid removed endoscopically do not have the swelling come back or need another surgery for healing problems. However, about 11.5% of patients may need a second procedure after the first one. If you have hard cords of tissue in the area, you might feel less satisfied with the final result compared to those without them.

What we can do about it

For most cases, you can start with self-care and rest. Your surgeon may suggest avoiding pressure on your elbow and using ice packs. Recent evidence shows that noninvasive management is often better than injections or surgery for initial treatment of nonseptic olecranon bursitis. You should give this approach time to work before trying more aggressive steps. If the swelling does not go away, your surgeon will look for other causes, such as a rare infection, especially if the problem lasts a long time.

If simple rest is not enough, your surgeon might discuss medical options. For uncomplicated septic olecranon bursitis, empirical management with medication has been found effective without needing surgery. In some cases, deferring needle aspiration is a reasonable choice. For recurrent cases that do not respond to standard care, intrabursal doxycycline sclerotherapy may be an effective alternative to surgery. This involves injecting a medicine directly into the swollen sac to shrink it. Hydrothermal ablation is another option where heat between 50C and 52C is used to treat chronic bursitis safely. This method has fewer complications than open surgery and works just as well.

Surgery is considered when conservative care fails or the bursitis keeps coming back. Your surgeon may recommend surgical excision to completely remove the bursa if you have had recurrent or failed conservative treatment. This leads to good clinical and functional outcomes for most people. In specific cases, such as chronic traumatic bursitis, a bursal suture repair might be used instead to keep the bursa intact while fixing the problem. Endoscopic debridement combined with a compression suture is also an option that is minimally invasive and allows for rapid recovery with minimal pain.

When to see someone

See your GP if your elbow stays swollen and painful despite resting, or if symptoms stop you from sleeping or working. Ask for a specialist review if the swelling keeps coming back, as this could signal a rare infection. You might also need help if you feel sudden weakness, your elbow locks, or it gives way. Distinguishing between simple swelling and infection can be hard, so get checked if things suddenly get worse. While most cases improve without surgery, some patients need a procedure to remove the swollen bursa, which has an 11.5% chance of needing another operation.
