The olecranon bursa
The olecranon is the bony tip of the elbow. Between this bone and the skin is a bursa, a small pocket that facilitates sliding. It usually contains little liquid. When it becomes irritated or inflamed, it can fill more and form a visible swelling.
This problem is different from tendinopathy on the side of the elbow and swelling inside the joint. The term bursitis describes the affected pocket, but does not specify its cause. Irritation related to support, an infection or an inflammatory disease are not treated in the same way.

Understand the picture
The bursa is between the skin and the tip of the elbow
Skin
A small wound can be important for the risk of infection.
Bursa
This pocket helps tissues slide over each other and can fill with liquid.
Olecranon
The bony point receives pressure when you lean on the elbow.

How swelling may present
The tip of the elbow can form a soft bump, sometimes quite large. It may be slightly painful or tender when you lean on the elbow and bend your arm. The movement sometimes remains quite free despite a visible volume. The appearance can be worrying even when the function is little changed.
Redness, warmth, pain and possible discharge should be described. The red color may be less visible on dark skin; also compare heat and evolution. A marked reduction in movement or deep pain can point to other problems. A photograph cannot be used to diinsect bite or punctureuish infected bursitis from uninfected bursitis with certainty.

Support, trauma and other causes
Repeated pressure on a hard surface or direct impact can irritate the bursa. A small break in the skin can allow bacteria to enter and cause an infection. Diseases such as gout or polyarthritis can also be associated with swelling in this area.
Mention a wound, insect bite or puncture, prolonged activity, or similar episode. Also report treatments that reduce immune defenses and your known illnesses. Sometimes no obvious trigger is found. The approach consists of looking for the cause useful for treatment, without concluding that any bump simply comes from leaning on your elbows.

When to consult the same day
Seek advice the same day if the area becomes red, hot, very painful or if the skin leaks fluid. A fever, chills or feeling unwell reinforce this need. The absence of fever is not enough to rule out an infection, especially if the immune system is weakened.
After a blow with significant difficulty moving, deformity or bone pain, a fracture must also be looked for. A cold, pale or numb hand requires urgent help. Do not puncture the pocket or heavily massage a hot area. An infection requires medical attention; a physiotherapy appointment should not delay it.
The examination and possible puncture
The doctor examines the skin, bursa, mobility and general signs. They look for an injury, associated illness, or other joint swelling. An x-ray can be useful in certain contexts, for example after trauma or to look for bone changes.
If an infection or crystals are suspected, a puncture may be discussed to analyze the fluid. It is not obligatory for any bump and must be carried out in a suitable setting. The doctor assesses its benefits and risks. Never attempt to empty the bursa with a needle at home, even if the skin appears easy to reach.

Care of uninfected bursitis
After assessment, reducing direct pressure can allow the bursa to calm down. Temporarily avoid prolonged support on a hard edge and use wider support if necessary. Local protection or adaptation of the workstation may be offered.
Pain treatment is chosen with the doctor or pharmacist depending on your health. A pocket that is still visible does not necessarily mean that you need to increase the number of invasive procedures. The swelling may take time to go down. The important thing is that the pain, skin and function improve favorably, without the appearance of redness, warmth or other signs of infection.

In everyday life
When there is a swollen pocket at the elbow
Observe
Look for heat, redness, pain, a wound or feeling unwell.
Have it evaluated
Seek medical advice the same day if these signs are present.
Adapt
After clarification, reduce weight bearing and follow the planned treatment.

If the bursa is infected or remains very bothersome
An infection may require antibiotics and sometimes drainage, depending on the evaluation. Tests and evolution guide care. Don’t reuse an old antibiotic or assume that an anti-inflammatory is enough. Contact the team quickly if the signs spread or if the general condition deteriorates.
Persistent or recurrent bursitis may require specialist advice. Intervention is sometimes discussed when other options are not enough. Corticosteroid injections are not a routine procedure and require consideration of infection and local risks. Ask what specific problem the proposed treatment is intended to address and how its effect will be monitored.

Physiotherapy and movement
Physiotherapy is not the treatment for an infection of the bursa. After clarifying the cause, it can help adapt supports and maintain or regain useful mobility. An elbow that moves comfortably does not necessarily need an intensive program to make the pocket disappear.
General exercises should not place pressure on the tip of the elbow. Avoid rolling directly over the bump with a ball or roller. If any movement significantly increases swelling, pain or warmth, stop and seek advice. The program must respect a possible wound, an intervention or the restrictions given by the doctor.
Office, DIY, sport and sleep
In the office, observe if the tip of the elbow rests for a long time on an armrest or the edge of the table. Supporting a larger surface area and changing position can reduce pressure. For DIY, alternate tasks and avoid kneeling with all the weight on your elbows.
In a sport with impact or support, protection can be discussed, without guaranteeing the absence of recurrence. To sleep, look for a position that does not press directly on the sensitive area. If a dressing is prescribed, keep it on as directed. These adaptations accompany care; they do not allow you to treat a swelling suspected of infection yourself.

Progress and monitoring
Uninfected bursitis may gradually improve, while the pocket remains visible for some time. Episodes may return if constraints persist or if an associated cause is not addressed. Above all, monitor pain, skin, overall volume and possible activities.
Check again if the swelling does not go down, if it recurs often, or if the diagnosis is unclear. Any spreading redness, new heat, fever or discharge requires prompt attention. After an intervention, skin care and resumption of weight bearing must be explained. There is not an identical time for the bump to disappear for each person.

Your questions
Can I have an infection without a fever?
Yes. A red, warm, painful, or leaky bursa can be infected without a high fever. Have it evaluated the same day, particularly in the case of diabetes or treatment that reduces immune defenses. A photo alone cannot exclude this cause.
Chapter sources [1]
Does the bursa always need draining?
No. The puncture responds to a specific indication, for example analyzing a suspicious liquid or treating certain situations. It carries risks and does not always prevent recurrence. The doctor compares its benefits to that of monitoring and other care.
Chapter sources [1]
Will the exercises deflate the bursa?
They are not a guaranteed way to empty the pocket. They can assist mobility when appropriate. Adapting supports and treating the cause are essential; an infection requires medical attention.
Chapter sources [1]
Can I continue to lean with protection?
A pad can reduce pressure, but it does not make prolonged pressure automatically suitable. Try to vary positions and distribute support. If heat, pain, or swelling increases, have the situation reevaluated.
