Trigger finger

Trigger finger is a condition that causes the finger to lock in a bent position that is extremely difficult to straighten out again. The position the finger is locked in is as if it’s resting on a trigger, which is where it gets its name.

What is trigger finger?

Trigger finger is a fairly common condition with a variety of causes. What they all have in common is that they result in overstraining the tendons and muscles in the hand and fingers. The condition is seldom seen in younger adults, but no one’s completely sure what exactly causes trigger finger. It may be overstraining or pressure on the tendon that causes localised swelling. The pressure on the tendon sheath limits the movement in the affected area and causes the tendon to “get stuck”.

How can trigger finger be treated?

If you go to your doctor, you may be treated with corticosteroid injections, which can mitigate the irritation in the tissue – a process that may need to be repeated every few weeks or months. Other forms of treatment may include relieving the strain on the finger combined with anti-inflammatory medication. Finally, physiotherapy or occupational therapy may prove to be successful.

Can the pain associated with trigger finger be relieved?

Minimising the strain on the finger may alleviate the pain and discomfort. If you think the injury is due to working with a computer mouse, it may be advisable to change your working methods. You can even swap your mouse for a more ergonomic mouse, which will relieve the strain on your hands and fingers by enabling you to use both hands and/or reducing the number of mouse clicks.

Note: If you develop symptoms of mouse arm that might be related to your job, you should speak to your employer or health and safety representative (HSR). If you work a lot with a computer, you can investigate the possibility of changing your work assignments or swapping your traditional computer mouse for an ergonomic mouse, as this may contribute to relieving your pain. If your symptoms persist, we advise you to contact your doctor.
