Elbow (Olecranon) Bursitis
Elbow bursitis (olecranon bursitis) is inflammation of the bursa (a small, fluid-filled sac) at the tip of the elbow that can cause visible swelling, tenderness, stiffness, and pain. Sometimes called student’s elbow or Popeye elbow, this elbow condition can make bending the joint, leaning on the arm, or performing everyday activities uncomfortable. Although elbow bursitis can look alarming, it often improves with non-surgical treatment.
What Is Elbow Bursitis?
Elbow bursitis is inflammation of the olecranon bursa, which cushions the tip of the elbow and reduces friction during movement. This causes the bursa to swell, creating a painful or tender lump at the back of the elbow. Elbow bursitis may result from repeated pressure, injury, infection or underlying inflammatory conditions.
Elbow Bursitis Symptoms
Elbow bursitis symptoms often begin with swelling at the bony tip of the elbow caused by inflammation of the olecranon bursa. The swelling may look like a soft, puffy lump the size of a golf ball, and can be accompanied by tenderness, pain, stiffness or reduced elbow movement. If the bursa becomes infected, the skin may feel warm, look red, and symptoms may worsen quickly.
Common elbow bursitis symptoms include:
- Visible swelling or a soft, fluid-filled lump at the back of the elbow
- Tenderness or pain, especially with direct pressure or bending the elbow
- Stiffness or reduced ability to fully bend or straighten the arm
- Warmth or redness over the swollen area
- Increasing pain or swelling over time
- Fever or chills, which may indicate septic elbow bursitis (infection)
Common Risk Factors for Elbow Bursitis
Elbow olecranon bursitis causes often involve repeated pressure, direct trauma, infection or underlying inflammatory conditions that irritate the bursa over time.
Common risk factors for elbow bursitis include:
- Repeated pressure from leaning on hard surfaces, desks, or armrests for long periods
- Jobs that place frequent pressure on the elbows, such as plumbing, painting, mechanical work or HVAC repair
- Repetitive elbow movement in sports such as baseball, tennis or golf
- Falls, direct blows, or other injuries to the back of the elbow
- Cuts, scrapes, insect bites, or other skin breaks that allow bacteria into the bursa
- Inflammatory conditions such as gout, rheumatoid arthritis or psoriatic arthritis
Types of Elbow Bursitis
Most cases of elbow bursitis involve the olecranon bursa at the tip of the elbow. Olecranon bursitis may develop suddenly after an injury, gradually from repeated pressure or as a result of infection or underlying inflammatory conditions.
- Acute elbow bursitis: Develops quickly after trauma, such as a direct blow or a fall onto the elbow, causing rapid swelling and discomfort.
- Chronic elbow bursitis: Develops gradually from repeated pressure, leaning on the elbow or repetitive motion over time.
- Septic elbow bursitis: Occurs when bacteria enter the bursa through a cut, scrape, insect bite or other break in the skin. This type often causes worsening pain, redness, warmth and fever and requires prompt treatment.
- Aseptic (non-infectious) elbow bursitis: Develops without infection and may be linked to inflammatory conditions such as gout or rheumatoid arthritis.
How Long Does Elbow Bursitis Last?
How long elbow bursitis lasts depends on the cause and severity of the inflammation. Mild cases may improve within one to three weeks, while most non-infected elbow bursitis resolves within three to six weeks with rest, activity modification and avoiding pressure on the elbow. Chronic or recurrent cases may take six to 10 weeks or longer to fully improve. If elbow bursitis is caused by infection, antibiotics or other medical treatment may be needed, though symptoms often begin improving once treatment starts.
When to See a Medical Provider for Elbow Bursitis
Seek medical care for elbow bursitis if swelling, pain, or limited movement do not improve with rest or if symptoms interfere with your daily activities. Prompt evaluation is critical if redness, warmth, fever, chills, or rapidly worsening swelling suggest infection.
