Swelling on the Tip of the Elbow? Here's What It Means and What to Do
Updated July 20261 minute read
A soft, fluid-filled swelling at the very tip of the elbow is usually olecranon bursitis — irritation of the bursa there, often from leaning on the elbow or a knock. It's frequently more swollen than painful and often settles once you stop pressing on it. The key safety point: if the swelling is hot, red, very tender, or comes with fever, it may be infected and needs urgent medical care.
What this usually means
Most likely causes. Olecranon bursitis from leaning, pressure, or a knock is the leading cause of a swollen elbow tip. Less common causes. Gout or, importantly, infection can cause a swollen, painful elbow tip; a bony injury can swell after trauma.
What you can try at home
For a non-painful, non-infected swelling, avoid leaning on or pressing the elbow (use a cushion or elbow pad), and give it time. Watch closely for signs of infection. Avoid repeatedly draining or squeezing it yourself.
When to see a physical therapist
For non-infected, lingering bursitis, a PT can help offload the area and address contributing habits. If infection is possible, see a physician first.
Red flags — don't wait
Seek urgent medical care if the swelling is hot, red, very tender, or comes with fever (possible infection), or if it follows a significant injury with deformity.
How a PT treats this
For non-infected bursitis, treatment offloads pressure, restores comfortable motion, and addresses habits like leaning on the elbow.
