9. Bursitis

Description: Inflammation of a bursa (fluid-filled sac) that cushions a muscle or tendon as it passes over a joint. The inflammation causes pain around the joint area, which often becomes more severe during exercise. One of the most common sites is the hip, where pain comes on gradually due to the repeated movement of tendons over the pelvis. It is generally caused by overuse and/or inflexibility, with the tight muscles causing increased friction – but it can also be a result of an impact or arthritis.

Treatment: T he root cause of the problem should be identified. Following assessment, a sports therapist may recommend anti-inflammatory medication and stretching. More severe cases can be treated with a cortisone injection. Training volumes, running surfaces, camber, technique, gait, shoe type and how well-worn your shoes are can all affect the gait cycle – and so these should be evaluated during assessment.

Training and racing: To be avoided while injured and initially post-injury. Only start training again when you're ready. A thorough warm-up and stretching routine will help to maintain muscle and tendon flexibility, which will limit friction.
