What is Trigger Finger?

 

Throughout the day, holding or grasping an object, typing on computers or smartphones, flipping books are the simple motion that can be easily done by using our fingers. However, these tasks might become complicated when the fingers are affected by certain painful condition, which is called trigger finger, also known as stenosing tenosynovitis. This occurs when the tendons that flex your finger are inflamed, leading to finger stiffness and pain, thus the finger will be difficult to bend and straighten. It can also be caused by a repeated movement or forceful use of your fingers or thumbs.  It can affect more than one finger at one time and on both hands.

What Are the Risk Factors for Trigger Finger?

Things that make you more likely to get trigger finger include:

  • Age: It usually shows up between ages 40 and 60.
  • Sex: It’s more common in women than men.
  • Health conditions: Diabetesgout, and rheumatoid arthritis can cause trigger finger.
  • Job: It’s common among farmers, industrial workers, musicians, and anyone else who repeats finger and thumb movements.
