Bursitis

Also called Housemaid's knee, Student's elbow, or Trochanteric bursitis

Bursitis is when a bursa, a small fluid-filled sac that cushions a joint, becomes inflamed. It often affects the shoulder, elbow, hip or knee and is usually caused by repeated pressure or overuse, such as kneeling or leaning on the elbows. It usually gets better on its own within a few weeks.

What it is

Rest, ice, painkillers and avoiding pressure on the area usually help. Physiotherapy or a steroid injection may be offered if it does not settle.

Occasionally bursitis is caused by infection, which needs antibiotics and sometimes draining.

Common signs

  • Pain and tenderness around a joint
  • Swelling
  • Pain that is worse when moving or pressing on the area
  • Redness and warmth if infected

How it is usually diagnosed

  • Examination
  • Ultrasound in some cases
  • Fluid taken from the bursa if infection is suspected

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Ultrasound reports
  • Fluid test results
  • Physiotherapy notes and injection dates

Questions to ask your doctor

  • What caused it, and how do I avoid it coming back?
  • Would physiotherapy or an injection help?
  • How can I tell if it is infected?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A hot, red, swollen joint area with fever
