What is elbow bursitis?

Elbow (olecranon) bursitis is inflammation and swelling of the elbow bursa, which is a thin fluid-filled sac at the tip of the elbow. The bursa can’t usually be felt or seen unless it becomes inflamed and swollen.

If the swelling is mild, you may not have any pain. But, sometimes, with more swelling, there can be pain or the back of the elbow may have a soft, golf ball shaped bump over the back of it.

Olecranon bursitis can be caused by a variety of factors such as elbow injury, infection, arthritis, leaning on the elbow too much, and strain from overuse.


  • Swelling in the back of the elbow
  • Pain in your elbow
  • Fever, warmth, and/or red discoloration if it’s infected


Treatment usually includes avoiding activities, wearing a brace, and taking antiinflammatory pain medications like ibuprofen (Advil).
