By Mayo Clinic staff
Imaging tests
If it appears that something else may be causing the discomfort, your physician may request an X-ray of the affected area. If bursitis is the cause, X-ray images can't positively establish the diagnosis, but they can help to exclude other causes of your discomfort.
Lab tests
Although you usually can trace bursitis to events of overuse or pressure, there may be no obvious cause. In the latter case, your doctor may want to perform additional screening to rule out other causes of joint inflammation and pain. This may include blood tests or an analysis of fluid from the inflamed bursa.
