How do you diagnose de Quervain tenosynovitis?
De Quervain is easily diagnosed by your doctor by taking a careful history and performing a physical examination.
A useful test you can try yourself is Eichoff's test: make a fist wrapping your fingers around your thumb then gently angle your wrist down away from your thumb. Be careful, this can be very painful!
When you attend your appointment an in-clinic ultrasound scan may be used to help confirm the diagnosis.
