The most common causes of bursitis are repetitive motions or positions that irritate the bursae around a joint. Examples include:

  • Throwing a baseball or lifting something over your head repeatedly
  • Leaning on your elbows for long periods
  • Extensive kneeling for tasks such as laying carpet or scrubbing floors
  • Prolonged sitting, particularly on hard surfaces

Other causes include injury or trauma to the affected area, inflammatory arthritis such as rheumatoid arthritis, gout, and infection.
