Stenosing tenosynovitis, more commonly known as trigger finger, is inflammation of the tendon sheath. This condition causes the affected finger to lock in a bent position and ranges from mildly annoying to very painful, depending on the severity. Medical intervention is often necessary for immediate relief, including surgery for more severe cases. Occupations that require repetitive motions such as typing or gripping exacerbate this condition. Trigger finger is also common among people with diabetes, osteoarthritis, and rheumatoid arthritis.
Long-term exposure to repetitive motions causes the tendon sheaths in the fingers to swell and become painful. Although the actual cause of trigger finger is unknown, the effects can be far-reaching. The pain eventually interferes with daily activities and can lead to other issues such as sleep deprivation, dependency on painkillers or anti-depressants, mood swings, and behavioral changes. Dependent on how long one deals with the pain, other symptoms such as loss of appetite, unexplained weight loss or gain, and lack of concentration can adversely affect wellbeing.
