Your GP will usually be able to diagnose bursitis by examining the affected body part and asking about your symptoms.
You may be asked whether you have recently fallen on the joint, or whether you have a job or hobby that involves repetitively using the affected area of your body.
Fluid sample
If you have a fever – a temperature of 38ºC (100.4ºF) or above – your GP may remove a small sample of fluid from the affected bursa.
The fluid is removed using a needle during a procedure known as aspiration and the sample sent to a laboratory to be tested for bacteria, which indicates a bacterial infection (septic bursitis). The sample may also be checked for crystals, which can develop due to conditions such as gout.
Following aspiration, a dressing is placed over the area and you will need to avoid strenuous activity for a couple of days.
Further testing
Further tests are usually only required if your symptoms do not respond to treatment. If this is the case, it will be necessary to rule out other conditions that may be responsible for your symptoms.
Further tests may include:
- an X-ray – to rule out fractures or broken bones
- blood tests – to rule out conditions such as rheumatoid arthritis
- magnetic resonance imaging (MRI) – to rule out tissue damage, such as a torn tendon (tendons are the cords that join bones to muscles)
