Repetitive strain or overuse of a tendon during activities such as sports, work, or hobbies is the most common cause of tendinopathy. Common factors that may put stress on the tendon include:
- Repetitive physical movements
- High-intensity training
- Muscle strain
- Poor posture
- Improper technique
- Lack of flexibility
- Lack of strength
Tendinopathy may become chronic when you experience frequent minor injuries that do not heal completely. Repeated activities, in this case, may cause collagen fibers to break down over time.
Tendinopathy is not seen in athletes alone. People who work jobs requiring repetitive actions or who lead sedentary lifestyles can also develop the condition.
An inactive lifestyle contributes to poor blood circulation in the tendons. When someone with poor blood circulation suddenly increases their activity, it may put stress on the tendon, causing inflammation and pain.
Tendinopathy can affect people of all ages, but some people are more likely than others to develop tendinopathy. Risk factors for tendinopathy include:
- Older age
- Jobs requiring repetitive motion
- Certain medications, like fluoroquinolones
- Certain medical conditions, like gout, diabetes, or dyslipidemia
- Unhealthy weight
- Poor muscle strength
