Trigger finger is an issue with the hand tendons that makes it hard to straighten one or several fingers after they were flexed.
A sheath or cover borders the tendons that go to the fingers. These tendons typically glide smoothly via the sheaths. If an individual has trigger finger, there is irritation and solidifying of a tendon sheath that ensnares the tendons or results to difficulty for the tendon to move via the sheath.
What is the cause?
The root cause of trigger finger is unknown. In some cases, it can be caused by overuse of the hand and fingers such as from sports or work where the fingers are used excessively. In some instances, it is likely to occur if an individual has rheumatoid arthritis or diabetes.
What are the signs?
Trigger finger can develop in the thumb or any finger, but the ring and middle finger are typically affected.
The usual signs include the following:
- A snapping, popping or abrupt jerking motion when attempting to straighten the finger
- Unable to straighten the finger
- Discomfort at the base of the finger or palm or in the fingers
Management of trigger finger
Generally, the doctor might administer a shot of steroid to lessen the swelling and irritation. This will allow the tendon to glide easily via the sheath. In some instances, surgery is necessary to remove a section of the tendon sheath.
Some of the self-care measures for the pain and swelling include:
- Apply an ice pack or cold compress on the site several times throughout the day.
- A pain medication can be taken based on the packaging instructions
