How is de Quervain’s tenosynovitis diagnosed?
To diagnose de Quervain's tenosynovitis, your doctor may do a simple test called the Finkelstein test. First, you bend your thumb so it rests across your palm. Then you make a fist, closing your fingers over your thumb. Last, you bend your wrist toward your little finger. If you have tenderness or pain at the base of your thumb, you probably have de Quervain's tenosynovitis.
