Carpal Tunnel Syndrome
Carpal tunnel syndrome is pressure on the median nerve as it passes through a narrow tunnel in the wrist. It causes numbness, tingling, and sometimes weakness in the thumb and first fingers, and it is one of the most common nerve compression problems in adults. Symptoms often start at night and gradually appear during daily activities.
Common symptoms
- Numbness or tingling in the thumb, index, middle, and part of the ring finger
- Symptoms that wake you at night or appear when driving or holding a phone
- Shaking the hand to "wake it up"
- Weak grip or dropping objects
- In advanced cases, visible thinning of the muscle at the base of the thumb
When to see a specialist
Mild or recent symptoms are typically treated first with a night splint, activity adjustments, and sometimes a steroid injection. See a physician sooner if numbness becomes constant, grip weakens, or thumb muscle bulk shrinks, long-standing nerve compression recovers less completely. A hand surgeon can confirm the diagnosis, often with a nerve study, and advise whether release surgery makes sense.
Treatment options
Common questions
- Does carpal tunnel syndrome always need surgery?
- No. Many mild cases improve with splinting and activity changes, and injections help some people for months or longer. Surgery is typically recommended when symptoms persist, worsen, or show signs of nerve damage.
- What happens if carpal tunnel is left untreated?
- Mild cases may stay stable or fluctuate, but ongoing significant compression can lead to constant numbness and permanent weakness. That is why worsening symptoms warrant evaluation rather than waiting indefinitely.
- How effective is carpal tunnel release?
- Release surgery reliably relieves pressure on the nerve, and night symptoms often improve quickly. Long-standing numbness may improve slowly or only partially, which your surgeon can help you anticipate.
