Symptoms of trigger finger
NHS Choices Medical Reference
Trigger finger usually affects your thumb, ring finger or little finger. More than one finger can be affected and the condition may develop on both hands. It is more common in the right hand, possibly because most people are right handed.
Symptoms of trigger finger can include:
- pain at the base of the affected finger or thumb (or both) when you move the finger or thumb, and if you press on the area
- a nodule (a small growth or lump of tissue) at the base of the affected finger or thumb
- stiffness or clicking when you move the affected finger or thumb, particularly first thing in the morning
If the condition gets worse, your finger may get stuck in a bent position and then suddenly pop straight. Eventually, it may not fully straighten.
Trigger finger in children
In a very small number of children between the ages of 18 months and three years old, trigger finger can affect the thumb. The main symptom will be an inability to fully straighten the thumb.
