Bursitis Causes & Risks


Acute bursitis may be caused by:

  • A blow to an area containing a bursa
  • Overexertion of a joint (eg, swimming a long distance or throwing a ball many times)

Chronic bursitis is usually caused by long-term overuse. The repeated motion of a muscle-tendon unit causes friction in the bursa. As the activity continues, the bursa becomes inflamed. It may fill with fluid. The bursa thickens and does not function well. Both bursa and tendon may become irritated.

Risk Factors

Factors that increase your chance for bursitis include:

  • Repetitive motion activities when done to an extreme (eg, swimming, running, or tennis)
  • Contact sports
  • Sporting gear that does not fit well
