Most cases of olecranon bursitis, the swollen fluid-filled bump on the back of your elbow, heal with simple at-home care in three to six weeks. The key is reducing pressure on the bursa, controlling inflammation, and knowing when the swelling signals something more serious like an infection.
What’s Happening Inside Your Elbow
The olecranon bursa is a thin, fluid-filled sac that sits over the bony tip of your elbow. It normally helps your skin glide smoothly over the bone. When it becomes irritated from a direct hit, repetitive leaning, or infection, it fills with extra fluid and swells, sometimes dramatically. The result is a soft, golf-ball-sized lump that can be tender, warm, or painful to bend.
The distinction that matters most for treatment is whether the bursitis is aseptic (not infected) or septic (infected). Aseptic bursitis is far more common and responds well to conservative care. Septic bursitis requires antibiotics and sometimes drainage. Redness that spreads beyond the elbow, fever, increasing warmth, and rapidly worsening pain all point toward infection.
First-Line Treatment at Home
For non-infected olecranon bursitis, the standard approach is rest, ice, compression, and elevation combined with an over-the-counter anti-inflammatory like ibuprofen or naproxen. Here’s what that looks like in practice:
- Rest: Stop the activity that triggered the swelling. If you lean on your elbows at a desk, change your setup so the point of your elbow doesn’t bear weight.
- Ice: Apply an ice pack wrapped in a cloth for 15 to 20 minutes several times a day, especially in the first few days when swelling is at its peak.
- Compression: A light compression bandage or elbow sleeve can help limit fluid accumulation, but don’t wrap so tightly that you cut off circulation.
- Elevation: Prop your arm up on a pillow when you’re sitting or lying down to help fluid drain away from the bursa.
This combination resolves most cases within three to six weeks. The swelling often improves noticeably in the first week or two, but the bursa can stay slightly puffy for a while even after the pain is gone. Patience matters here. Continuing to irritate the elbow during this window is the most common reason bursitis lingers.
When Fluid Needs to Be Drained
If your elbow hasn’t improved after three to six weeks of conservative care, or if the swelling is large enough to limit your range of motion, your provider may recommend aspiration. This involves inserting a needle into the bursa and drawing out the excess fluid. It provides immediate pressure relief and can help your elbow move more freely.
Aspiration also serves a diagnostic purpose. If there’s any concern about infection, analyzing the fluid is the most reliable way to tell. A high white blood cell count in the fluid, cloudy or pus-like appearance, and low glucose levels relative to your blood all suggest septic bursitis. When infection is suspected, aspiration isn’t optional. It’s necessary both to confirm the diagnosis and to identify which bacteria are involved.
Steroid Injections: Worth the Risk?
You may have heard that a corticosteroid injection into the bursa can speed recovery. The evidence is not encouraging for standard aseptic bursitis. A systematic review found that steroid injections for non-infected bursitis increased overall complications, including a significantly higher rate of skin thinning at the injection site. The injections did not improve outcomes compared to conservative treatment alone. The one exception is bursitis caused by gout, where uric acid crystals are driving the inflammation. In that specific situation, steroid injections can be effective.
Treatment for Infected Bursitis
Septic olecranon bursitis requires antibiotics. Most people can be treated at home with oral antibiotics. In one study of emergency department patients with suspected septic bursitis, 88% of those sent home on antibiotics without aspiration recovered without needing further procedures, hospitalization, or surgery.
The bacteria behind most cases is Staphylococcus aureus, including MRSA strains. About a third of outpatients in that study received antibiotics covering MRSA, while 77% of those sick enough to be admitted to the hospital did. Your provider will choose the antibiotic based on how severe the infection appears, your risk factors for resistant bacteria, and whether fluid culture results are available.
Signs that the infection is responding include decreasing redness, less warmth, and reduced pain over the first few days. If symptoms worsen or don’t improve, you may need a different antibiotic, fluid drainage, or inpatient treatment.
When Surgery Becomes Necessary
Surgery to remove the bursa entirely, called a bursectomy, is reserved for cases that don’t respond to other treatments. This typically means chronic bursitis that keeps coming back despite repeated drainage, or septic bursitis that fails to clear with antibiotics alone.
A bursectomy is an outpatient procedure. You go home the same day. Afterward, you’ll wear a splint or brace to keep your elbow stable while the area heals. Recovery takes about a month. Your body eventually forms new tissue where the bursa was, though the new sac may not be as robust as the original. The surgery is generally successful, but like any procedure, it carries risks of wound healing issues, especially at the elbow where skin is thin and sits directly over bone.
Exercises to Maintain Mobility
While your bursa heals, gentle stretching prevents stiffness without aggravating the swelling. Start slowly and stop if an exercise causes pain.
- Elbow extensor stretch: Raise your affected arm and bend the elbow with your palm facing you. Use your other hand to gently press the forearm toward your shoulder until you feel a stretch in the back of your upper arm. Hold for 15 to 30 seconds, and repeat two to four times.
- Wrist flexor stretch: Extend your affected arm in front of you, palm down, and bend your wrist back so your fingers point up. Use the other hand to gently increase the stretch. Hold 15 to 30 seconds, repeat two to four times. Then flip your palm up and bend the wrist the opposite direction.
- Forearm rotation: Keep your elbow at your side, bent at 90 degrees. Hold a pen or pencil and slowly rotate your forearm as far as comfortable in each direction. This maintains the rotational range you need for everyday tasks.
These aren’t aggressive rehab exercises. They’re maintenance stretches designed to keep your elbow, wrist, and forearm from tightening up while you limit activity during recovery.
Preventing Recurrence
Olecranon bursitis has a frustrating tendency to come back, especially if the original trigger hasn’t been addressed. The two most practical changes you can make are wearing elbow pads during physical activity and breaking the habit of leaning on hard surfaces.
If your work involves resting on your elbows (plumbing, HVAC, desk work), padded elbow sleeves create a buffer between the bone and whatever surface you’re pressing against. Even a small amount of cushioning makes a meaningful difference because the bursa sits right on the point of the elbow with almost no natural padding. People who lean on armrests or hard desks for hours are among the most common repeat cases. Repositioning so your forearm bears the weight instead of the elbow tip, or adding a soft pad to your work surface, reduces the chronic pressure that keeps the bursa inflamed.
