Elbow bursitis: the name describes a soft swelling on the tip of the elbow, often appearing within a few days, that looks much more serious than it usually is. The real question is not "how do I get rid of it", but another one: is it an inflamed bursa that will go down on its own once the cause is removed, or is it infected and needs to be seen today?
It is worth being clear from the start on one point that almost no article mentions: for the treatment of non-septic olecranon bursitis, the evidence is scarce and weak. A review published in the Journal of Hand Surgery says so plainly: there are no evidence-based recommendations, and the condition is often self-limiting. This does not make the article pointless: it changes the priorities. The important part is not choosing a miracle remedy, it is recognising infection and removing the pressure that created the problem.

First of all: when not to wait
About one third of cases are septic, meaning caused by an infection. The review that provides this figure pools elbow and kneecap bursitis together, so the number should be read as an order of magnitude for superficial bursitis in general. It is still a high proportion, which is why this section sits at the top and not at the bottom. See a doctor the same day, or go to A&E, if you notice:
- fever or shivering together with the swelling of the elbow;
- very red and hot skin, with the redness spreading beyond the swelling;
- a wound, graze or scab on the tip of the elbow, even a small one that has already healed over: it is the most common point of entry for bacteria;
- intense pain that is not explained by simple swelling, or difficulty bending the elbow;
- rapid worsening over a matter of hours;
- diabetes, immunosuppressive treatment, long-term cortisone or other conditions that lower your defences: the picture can be more aggressive and less noisy than expected.
A treatment algorithm developed from 52 studies lists as guiding signs of infection a body temperature above 37.8 °C, a skin temperature difference over the bursa greater than 2.2 °C compared with the healthy side, and the presence of skin lesions. These are clues, not verdicts: the real distinction is made by aspirating the fluid and analysing it.
What the olecranon bursa is and why it swells
On the tip of the elbow, between the skin and the bone, there is a flat sac that normally contains a thin film of fluid: its job is to let the skin slide over the bone without friction every time you rest on or bend your arm. It is an exposed structure, protected by very little tissue.
When that area is pressed or knocked for a long time, the bursa reacts by producing more fluid. The result is the typical swelling: soft, movable, often painless at first, which many people describe as "a water ball" or a small egg stuck to the elbow. The elbow usually still moves well, and this is an important difference from problems inside the joint itself, where movement is reduced.
One review of the literature estimates a minimum incidence of 10 cases per 100,000 people a year, with a marked male predominance (around 80% of cases) and a peak between the ages of 40 and 60. Here too there is an honest caveat: the authors report these figures together with elbow and kneecap bursitis, not olecranon bursitis alone.
The most common causes
In most cases there is repeated micro-trauma, not a single event:
- resting the elbows on a desk, a car armrest, a table or the floor for hours every day. It is the number one cause, and the most underestimated because it is an automatic gesture;
- jobs and sports that involve leaning or sliding on the elbows: floor layers, plumbers, electricians, people who work under a car, but also wrestling, volleyball and martial arts;
- a direct blow to the tip of the elbow, with swelling appearing over the following hours;
- a skin lesion that lets bacteria in, and this is the route to the septic form;
- diseases that inflame the joints, such as rheumatoid arthritis and gout, which can bring on bursitis even without micro-trauma, sometimes with small palpable nodules inside the bursa.
This list is not academic: in elbow bursitis the most effective treatment consists of removing the cause, so identifying it is half the work.
An important tip: before trying these exercises, make sure you have a correct diagnosis. People often assume they have one problem when the real source of the pain is something else. Doing the wrong exercises can make things worse instead of better.
Septic or non-septic: what helps tell them apart
A review published in the Journal of Shoulder and Elbow Surgery listed how often each clinical sign appears in the two forms, and the comparison is instructive:
| Sign | Septic bursitis | Non-septic bursitis |
|---|---|---|
| Pain on pressure | 88% | 36% |
| Redness / cellulitis | 83% | 27% |
| Local heat | 84% | 56% |
| Trauma or skin lesion | 50% | 25% |
| Fever | 38% | 0% |
Two readings, both important. The first: fever, widespread redness and clear pain on pressure shift suspicion strongly towards infection. The second, which popular articles always leave out: none of these signs is decisive on its own. Fever is absent in more than six septic bursitis in ten, and local heat is present in more than half of the non-infected ones. The same authors conclude that clinical and laboratory pictures overlap and that telling them apart can be difficult. Hence the practical rule: if in doubt, you aspirate and analyse, you do not guess.
What the studies really say about treatment
This is where the usual story is turned upside down. The most solid randomised trial, run in two centres, enrolled 133 patients and randomised 90 into three groups of 30: compression bandage with anti-inflammatories, aspiration of the fluid alone, and aspiration followed by steroid injection. Seven people dropped out of the follow-up. At four weeks:
- compression bandage + anti-inflammatories: 25 of 30 resolved (83%);
- aspiration alone: 17 of 26 (65%);
- aspiration + steroid: 23 of 27 (85%).
The differences between the three groups were not statistically significant. The steroid did, however, shorten the time to resolution: a median of 2.3 weeks against 3.1 for aspiration alone and 3.2 for compression. The only factor associated with failure at four weeks was how long the symptoms had lasted before treatment began.
A caveat that the authors themselves state clearly, and that it would be wrong to leave out: the study had the statistical power to detect only differences of 30% or more. "No difference found" therefore does not mean "equivalent treatments": a smaller difference would have gone unnoticed with these numbers, and the authors present their data as pilot data for larger future studies.
The largest systematic review, covering 29 studies and 1,278 patients, adds the other side of the coin. Cortisone injection in aseptic forms was associated with more complications overall and more skin atrophy, without improving the outcome. Surgery fared worse than conservative treatment across the board: fewer resolutions, more complications, more persistent drainage and more infections of the bursa. Aspiration, on the other hand, did not increase the risk of infection in aseptic forms. The authors note that the evidence is mostly level IV, that is, weak.
A systematic review from 2023 reaches the same conclusion by a different route: the two available randomised trials have a high risk of bias, and neither shows significant differences between the options; cortisone shortens the duration of symptoms but comes with more complications, including bursal infection and skin atrophy, and should therefore be reserved for refractory cases. To be fair, these same authors, in their conclusions, describe the injection as "more effective than the other treatments": they do not dismiss it, they place it second-line because of its price in complications. Finally, a review of interventions for elbow disorders classed the evidence on olecranon bursitis as "at most limited", while noting, and it is right to say so because it points in the opposite direction, limited evidence in favour of methylprednisolone injection combined with naproxen, based on a single randomised trial.
Put simply, in non-septic elbow bursitis the simple route (protect, compress, stop pressing) is competitive with the invasive ones, and does not carry their risks. Needles and cortisone are not forbidden: they are a shortcut on timing that is paid for in complications, and it makes sense to propose them when the swelling does not go away or when there is a concrete reason to speed things up.
It is worth adding that not all authors put the needle so far down the list. The treatment algorithm built on the 52 studies mentioned above includes aspiration of the bursa among the general measures, together with anti-inflammatories, rest, ice and compression, in both septic and non-septic forms, and provides for steroid injection in patients with a confirmed non-septic form and high sporting or work demands. This is not a contradiction, it is the same uncertainty seen from another angle: without strong evidence, each person weighs speed and risk differently. One more reason to decide with a professional who has seen your elbow, rather than with a rule taken from an article.
What to do in the first few days
If infection has been ruled out, in elbow bursitis the goal is just one: take the load off the bursa and give it time to reabsorb the fluid.
- Find the movement that presses on it and change it. This is the step that decides everything. Desk, car armrest, sofa, the way you get up from bed: for a few weeks that tip of the elbow must not rest on anything.
- Protect the tip of the elbow. A padded elbow pad or a strip of foam is there precisely to prevent resting on it at the moments you forget, and you will forget.
- Light compression. It is not the "winning" arm of the trial, since none was, the differences were not significant, but it is what the authors recommend because it offers the best balance between safety and effectiveness, without a needle. An elastic bandage wrapped without tightening, removed at night, that must never tingle or change colour in the fingers. In the study the bandage was applied in the clinic and the elbow was rechecked every week: if you are not sure how to wrap it, have it shown to you rather than improvising.
- Ice in the first days, wrapped in a cloth, if the elbow is warm and sore. It gives relief; it is not the cure.
- Anti-inflammatories only if you have no contraindications and after speaking with your doctor or pharmacist: in the randomised trial they were used alongside compression, not on their own.
- Keep moving the elbow. Bending and straightening without forcing maintains movement; it is resting on it that should be avoided, not moving it.
- Do not pierce or squeeze the swelling yourself. Aspiration is a sterile procedure done in a clinic: done at home it is the most direct way to turn a non-infected bursitis into an infected one.
If after two or three weeks the swelling is unchanged, if it returns every time you resume your activities, or if the pain increases, it needs reassessment, not a more aggressive remedy chosen on your own.
When the bursitis is infected
The septic form is a chapter of its own and is not managed independently. It is treated with antibiotics, usually after aspirating and analysing the fluid; in the most serious cases, refractory ones or ones with pus collection, drainage or surgical removal of the bursa is needed.
A retrospective analysis of 91 patients operated on for septic olecranon bursitis across the Mayo Clinic sites over twelve years gives an idea of real timescales: Staphylococcus aureus was the most frequent germ (64% of cases), healing was achieved in 87% of patients (79 out of 91), and post-operative complications affected 23% (21 out of 91). The median duration of antibiotic therapy after surgery was 21 days, calculated excluding the five patients who already had a blood or bone infection at onset, which require much longer courses. Active smokers had a roughly four and a half times higher chance of clinical failure than non-smokers. These are data from patients who had already been operated on, so they are the more demanding cases: most septic bursitis resolves without reaching the operating theatre, but the message stands that infection requires long timescales and medical supervision.
The reverse also holds: the review on the treatment algorithm found no evidence supporting immediate removal of the bursa in septic cases, and recommends starting with a conservative approach guided by the analysis of the fluid in any case.
Prevention and recurrences
Olecranon bursitis tends to come back, for the simple reason that the habits that caused it return before it does. Anyone who has had it should consider a padded elbow pad part of their work or sports kit, not a temporary remedy. Adjusting the height of the desk and chair armrest so that the forearm rests on its middle third and not on the tip of the elbow, taking breaks from prolonged leaning, covering scratches and grazes on the elbow straight away: these are simple measures, and they are what makes the difference in elbow bursitis between a single episode and a story that keeps repeating.
And physiotherapy?
Honesty again: there are no studies showing that exercises have an effect on the swelling of the olecranon bursa, and anyone promising you an exercise protocol to make it disappear is going beyond what we know. In this condition the physiotherapist does a different job, one that largely comes before and after the swelling.
It serves to understand which everyday movement keeps pressing on that elbow and how to really change it, not just in words. It serves to recognise the signs that call for an urgent medical assessment rather than a rehabilitation pathway. It serves to tell the picture apart from other elbow pains that are easily confused, such as golfer's elbow epicondylitis or a problem with the ulnar nerve at the elbow, which causes tingling in the fourth and fifth fingers. And it serves afterwards, to restore movement and strength if the arm has been spared for a long time.
All of this can be done well over a video call too: watching how you rest your elbow while you work, seeing the swelling, comparing colour and movement between the two sides, deciding together what to change in your day.
In summary
Elbow bursitis is almost always less serious than it looks, but it is also less "curable with the right trick" than it is often made out to be. The available evidence says three things: telling apart the septic form is the clinical priority; conservative treatment holds up well against invasive treatment; cortisone shortens the timescales but adds complications and should be kept for cases that do not go away. The rest is up to you: identifying the pressure that created the problem and stopping applying it.
