Can you get bursitis anywhere in the body?

Yes. Anywhere you have a bursa (joint pad), you can get bursitis. The most common areas of bursitis are the elbow, shoulder, hip, and just below the knee. There are also multiple bursae in some larger joints and a few joints that infrequently get bursitis.
