What causes bursitis?Bursitis typically results from repeated irritation to a particular bursa, such as overuse or excess pressure through from strenuous activity with high loads. This may be contributed to by poor biomechanics and function of the lower limbs. The irritation causes swelling and the onset of painful symptoms. Trauma/injury in the region of the bursa can also cause bursitis, as well as certain systemic inflammatory conditions, such as rheumatoid arthritis or gout. Any mechanism of action that causes a bursa to become inflamed will cause pain and tenderness at the bursa itself, as well as at the surrounding structures. This is due to the extra pressure on the tendons and muscles created by the swelling of the bursa that can then begin to irritate them. Bursitis is more common as we grow older and if our work involves repetitive movements.
What are the symptoms?The symptoms of bursitis can include:
- Pain and tenderness in the region of the affected bursa
- Tenderness in the surrounding tendons and structures
- Inflammation and swelling
- Stiffness in the region of the bursa
- Achilles tendon at the back of the heel
