Elbow Bursitis (Olecranon)

Swollen sac over the point of the elbow, from leaning, trauma, or infection.

Overview

what it is and why it matters

There is a small fluid-filled cushion called a bursa sitting directly over the bony point at the back of your elbow (the olecranon). It can fill up and swell when it gets irritated, most often from leaning on your elbow at a desk, getting bumped, or from gout, pseudogout, rheumatoid arthritis, or an infection working its way in. The classic look is a soft, bulging knot at the tip of the elbow that gives when you press on it. It usually does not hurt unless it is infected or actively inflamed. If it's infected (septic bursitis), it needs antibiotics, a different problem from the everyday irritation kind.

Symptoms

what you may notice
  • Soft, golf-ball-sized swelling at the elbow tip, a squishy lump right over the bony point you can press in with your finger.
  • Pain only if infected or actively inflamed, a simple fluid collection is usually painless; if the skin is hot and tender, infection is the concern.
  • Full range of motion preserved, you can still bend and straighten your elbow because the bursa sits outside the joint itself.
  • Warmth and redness over the swelling, if the skin turns red and feels warm, that points toward septic (infected) bursitis and needs prompt evaluation.

Diagnosis

exam first, imaging second

Soft, visible swelling right on the point of your elbow. You can usually still bend and straighten your arm fine, because the bursa sits outside the joint itself. To figure out which kind you have, your provider draws a small amount of fluid from the swelling with a needle (aspiration) and sends it to the lab. The lab counts cells, looks for crystals, and runs a culture; that tells us whether it's an infection, a gout flare, or just inflammation.

How We Treat It

what we try first, in order

Treatment depends on what is driving the swelling, which is why we usually draw a little fluid first to tell the difference between simple irritation, a gout flare, and an infection. The steps below are listed in the order we usually introduce them, the simplest measures first. One important rule runs through all of them: if there is any sign of infection, that gets treated before anything that could mask it.

First, take the pressure off

1

Padding and Activity Changes

Wear elbow pads, and stop resting your elbows on hard surfaces. For mild cases this alone often calms it down.

2

Aspiration

Drawing the fluid out with a needle (aspiration) both shrinks the swelling and lets the lab tell us what is driving it. The fluid often comes back if the underlying cause, leaning on the elbow, gout, or infection, is not fixed.

3

Anti-Inflammatory Pills

An over-the-counter anti-inflammatory like ibuprofen can take the edge off, but only once your provider has ruled out infection.

If the simple steps are not enough

  1. Corticosteroid Injection

    If aspiration alone does not quiet things down, a steroid shot into the bursa can help, but only when infection and crystals (gout) have been ruled out.

  2. Antibiotics

    Septic (infected) bursitis is treated with antibiotics, by IV in the hospital if it is serious, or by mouth if it is milder and the bug is sensitive to oral options.

Surgical Options

if non-operative care isn't enough

Surgery (bursectomy, removing the bursa entirely) is reserved for two stubborn cases: an infected bursa that won't clear with antibiotics and drainage, or a chronic one that keeps refilling no matter how many times it's drained or injected.

Frequently Asked

questions we hear in clinic
Does olecranon bursitis hurt?

Usually not. A simple fluid collection is generally painless, which is why many people notice the swelling before any discomfort. Pain shows up mainly when the bursa is infected or actively inflamed. If the skin over the swelling turns red and feels hot and tender, that points toward an infection and needs prompt evaluation.

Will it affect how I bend my elbow?

No. You can still bend and straighten your elbow normally, because the bursa sits outside the joint itself rather than inside it.

Why does my provider draw fluid from it?

Drawing a small amount of fluid with a needle (aspiration) does two things at once: it shrinks the swelling, and it lets the lab tell us what is driving it. The lab counts cells, looks for crystals, and runs a culture, which sorts out whether you are dealing with an infection, a gout flare, or simple inflammation.

Why does the swelling keep coming back after it is drained?

The fluid often refills if the underlying cause is not addressed. Leaning on the elbow, gout, or infection will keep feeding the bursa until that root cause is fixed, which is why padding, activity changes, and treating the specific cause matter alongside drainage.

Can I just take ibuprofen for it?

An over-the-counter anti-inflammatory like ibuprofen can take the edge off, but only once your provider has ruled out infection. Quieting an infected bursa with an anti-inflammatory before it has been identified can mask a problem that needs antibiotics instead.

Will I need surgery?

Rarely. Surgery to remove the bursa (bursectomy) is reserved for two stubborn situations: an infected bursa that will not clear with antibiotics and drainage, or a chronic one that keeps refilling no matter how many times it is drained or injected.
