Normally, each tendon moves easily within the tendon sheath. Overuse can inflame the tendon and cause grating and pain. The condition can become so serious that the patient can hear the tendon grating. This is known as tenosynovitis crepitans. A physician should be consulted at the first sign of pain.
Trigger finger is another type of mechanical disorder of a tendon.
A lump develops on the tendon of a finger through overuse. The patient wakes with a flexed and painful finger, which straightens with an audible and visible snap. Surgery is the primary treatment for the condition.
