Many people develop tendinitis owing to their hobbies or jobs involve repetitive motions that may put stress on the tendons. Using an appropriate technique is especially important when performing repetitive sports movements or job-related activities. Tendinitis is more common when occupations involve: Sports that involve repetitive movements/motions, particularly if your technique is not optimal can provoke tendinitis Examples are:

Overview

Using an appropriate technique is especially important when performing repetitive sports movements or job-related activities. Tendinitis is more common when occupations involve: Sports that involve repetitive movements/motions, particularly if your technique is not optimal can provoke tendinitis Examples are:
- Repetitive motions
- Awkward positions
- Frequent overhead reaching
- Vibration
- Forceful exertion
- Baseball
What happens in the body
The condition involves changes in affected tissues or organ systems that produce the symptoms described below
- Underlying disease process affects how symptoms develop

- Other organs can be involved in moderate or severe cases
Causes and risk factors
Possible causes and contributing factors include:
- Exact cause may be multifactorial
- Age, genetics, and environment can influence risk
- Underlying medical conditions may increase susceptibility
Diagnosis and evaluation
