Tendonitis is an inflammation of a tendon, a band of connective tissue that connects a bone and a muscle.
It can be associated with a wide range of factors that place repetitive or ongoing strain on the tendons, including:
- Sporting activities such as running, jumping, or other high impact activities, especially when performed on hard surfaces
- Lifting heavy weights
- Poor sporting technique (for example, an incorrect golf swing, or the use of sporting equipment that is too heavy)
- Maintaining awkward positions for long periods of time
- Being obese
Tendonitis is more likely to occur if you don’t warm up properly prior to exercising, if you exercise in cold environments, or if you don’t allow sufficient recovery time between exercise sessions.
Other contributing factors may include the presence of bony spurs on the heels or calcium deposits in the tendons.
