The bursa on the tip of the elbow can fill with fluid after a knock or from prolonged leaning, producing a soft swelling that can reach the size of a golf ball. It is often far less painful than it looks. The important thing is distinguishing a simple bursitis from an infected one, which needs medical treatment rather than physiotherapy.

What causes it

  • A direct blow to the point of the elbow
  • Prolonged leaning on hard surfaces — desks, car doors, floors
  • Repeated minor trauma in trades work
  • Gout or rheumatoid arthritis
  • Infection, which changes the management entirely

What you might notice

  • A soft, fluid-filled swelling on the tip of the elbow
  • Often minimal pain relative to the size of the swelling
  • Discomfort resting the elbow on a surface
  • Some loss of full bend if the swelling is large
  • Redness, heat, spreading pain or feeling unwell — which point to infection

How we treat it

  • Ruling out infection first — red, hot, painful or feverish needs a doctor the same day
  • Removing the source of pressure, which is often all that is needed
  • Padding or a sleeve to protect it while it settles
  • Range of movement work to prevent stiffness
  • Strengthening back through the arm once the swelling has gone
  • Referral for drainage where it persists or limits function

This page is general information, not a diagnosis. Symptoms overlap between conditions, so the right treatment depends on an assessment. If your pain followed a significant injury, is getting worse, or comes with numbness, weakness or unexplained weight loss, please see your GP.

If it is red, hot or you feel unwell, see a doctor today

An infected bursa needs antibiotics, not physiotherapy. If it is simply swollen and uncomfortable, we can sort out why it keeps filling and stop it happening again.
