Questions & Answers · Hand & Wrist
How do I know if I have carpal tunnel syndrome?
The classic carpal tunnel signature: numbness and tingling in the thumb, index, and middle fingers — worst at night or first thing in the morning — often relieved by shaking your hand out. The pinky staying normal is a telling detail: a different nerve serves it. Weeks of nightly wake-ups, a weakening grip, or dropped coffee cups mean it's time to stop calling it "my hand falling asleep."
Why the pinky matters, and other clues
- The median nerve runs through the carpal tunnel and serves thumb-side fingers — the pinky belongs to another nerve. Whole-hand or pinky-included numbness points elsewhere (sometimes the neck), which is exactly why a specialist exam beats a guess.
- Night is prime time: curled sleeping wrists narrow the tunnel; the shake-it-out wake-up is nearly diagnostic.
- The escalation: tingling → constant numbness → weak grip → muscle loss at the thumb base. That last stage can be permanent — the whole case for not waiting years.
What treatment actually looks like
Early cases: night splints and activity changes genuinely work. Persistent cases: an injection can calm the nerve, and nerve testing (done on-site) confirms severity. When surgery is right, carpal tunnel release is one of medicine's most reliable operations — Dr. Jackson has spent two decades on it, and most patients are using the hand lightly within days.
