Tendonitis
Tendonitis is the painful inflammation
of a tendon and its ligaments, which attach it to the bone.
It often results from the stress of repetitive movements.
Acute tendonitis may become chronic if it is not treated.
The areas most commonly affected by tendonitis are the
shoulder (rotator cuff tendonitis or impingement syndrome),
elbow (tennis elbow or golfer's elbow), wrist and thumb (de
Quervain's disease), knee (jumper's knee), and ankle (Achilles
tendonitis). Calcific tendonitis, which occurs when calcium
deposits build up in a joint, often appears in people with
a chronic disease, such as diabetes.
Signs and Symptoms
- Minor edema (swelling)
- Tenderness in affected limb
- Pain that worsens when you move the affected limb
- Warmth and redness
- Crepitus (crackling)
What Causes It?
Although the exact cause of tendonitis is unknown, it
can result from overuse, under training, or poor technique
in sports, repetitive movement in certain occupations, falling,
lifting or carrying heavy objects, and extreme or repeated
trauma. It may also be seen with certain inflammatory conditions
(for example, Reiter's syndrome, ankylosing spondylitis), autoimmune
disorders (for example, diabetes mellitus), and some infections.
