Diagnosis is made on interview and physical examination. More than one finger may be affected at a time. It is most common in the thumb and ring finger. The triggering more often occurs while gripping an object firmly or during sleep when the palm of the subject’s hand remains closed for an extended period of time, presumably because the enlargement of the tendon is maximum when the finger is not being used. Upon waking, the affected person may have to force the triggered fingers open with their other hand. In some, this can be a daily occurrence.
