- Popping, clicking or catching when they move their thumb
- Thumb locked in a bent position
You child may also have these symptoms:
- Pain and swelling in their thumb, usually near the base

Trigger Thumb Diagnosis
Doctors can diagnose trigger thumb by asking about your child’s symptoms and doing a physical exam.
If your child seems to have trigger thumb, the doctor will check to make sure they do not have some other problem, like a fractured bone or a joint that’s out of place (dislocated).
The doctor will also check for signs of broader health conditions that may affect the hands, like cerebral palsy or arthrogryposis. (Most children with trigger thumb do not have any other condition.)
