You wake up at 2 a.m. Your hand is numb. You shake it. The tingling fades. Then it comes back.
That pattern is one of the most common signs of carpal tunnel syndrome (CTS). It affects about 3% of adults, making it the most frequent nerve compression problem in the body. If your symptoms follow you into summer paddle sports, gardening, or long hours at a keyboard, you are not alone.
Here is what the research says about what causes CTS, how to recognize it, and what actually helps.
Research stat: A 2024 meta-analysis found that carpal tunnel syndrome is 2.5 times more common in women than in men, and risk rises sharply after age 50. (Gebrye et al., Musculoskeletal Care, 2024)
What Is Carpal Tunnel Syndrome?
Your wrist has a narrow passageway called the carpal tunnel. The median nerve runs through it, along with tendons that move your fingers. When that tunnel gets too tight, the nerve gets squeezed. That squeezing causes pain, numbness, and tingling in your thumb, index finger, middle finger, and half of your ring finger.
It does not affect your pinky. That is actually a useful clue. Pinky numbness usually points to a different nerve entirely.
What Causes Carpal Tunnel Syndrome?
No single cause explains every case. The most common contributors are repetitive hand and wrist movement, especially with a bent or twisted wrist. This is why CTS is common in office workers, mechanics, and people who grip paddles or rackets for hours at a time.
Medical conditions that cause swelling or fluid retention also raise the risk. Pregnancy, diabetes, thyroid problems, and rheumatoid arthritis are all on that list. Obesity and a family history of CTS matter too.
Age is a factor. The tunnel naturally gets smaller over time, leaving less room for the nerve to move freely.
How Do You Know If You Have Carpal Tunnel Syndrome?
The symptoms are hard to miss once they start. A 2024 retrospective study found that 85.7% of CTS patients reported nighttime symptoms, the kind that wake you up and make you shake your hand for relief. You may also notice tingling that spreads from the wrist toward the first three fingers, weakness when pinching or gripping, or a tendency to drop objects.
Symptoms often get worse when holding a phone, steering wheel, or book for a long time. A doctor can confirm the diagnosis with a nerve conduction test or simple physical tests like Phalen’s test, which involves holding the wrist bent for 60 seconds to reproduce the tingling.
What Are the Best Treatments for Carpal Tunnel Syndrome?
The right treatment depends on how severe your symptoms are. Most mild to moderate cases respond well to non-surgical care.
Wrist splints worn at night keep the wrist in a neutral position, reducing pressure on the nerve while you sleep. This alone helps many people, especially in the early stages.
Manual therapy is another solid option. A 2024 systematic review and meta-analysis of five randomized controlled trials with 533 participants found that manual therapy provided significantly better short-term pain relief at 1 and 3 months compared to surgery. By 6 to 12 months, both groups had similar quality-of-life outcomes, though surgery showed greater functional gains in severe cases.
Chiropractic care addresses nerve mobility and joint restrictions in the wrist and cervical spine that can contribute to symptoms. Learn how spinal care affects nerve function.
Corticosteroid injections reduce inflammation inside the tunnel and often provide months of relief. Surgery, which cuts the ligament that forms the roof of the tunnel, has excellent long-term success rates for severe or persistent cases.
Can Exercises Help Carpal Tunnel Syndrome?
Yes. Nerve gliding exercises are among the most studied conservative options. They help the median nerve slide freely through the tunnel rather than getting stuck.
A 2023 randomized controlled trial found that patients with mild CTS who added nerve and tendon gliding exercises to nighttime splinting had significantly better outcomes than those using splinting alone.
One basic nerve glide: Start with your wrist bent and fingers curled into your palm. Slowly straighten your fingers and extend your wrist back. Hold for a few seconds, then return. Repeat 5 to 10 times. Stop if it causes sharp pain.

How to Prevent Carpal Tunnel Syndrome
You cannot control every risk factor, but you can reduce nerve strain. Keep your wrists in a neutral position during repetitive tasks. Take short breaks from gripping tools or a keyboard every 30 to 45 minutes. Treat underlying conditions like diabetes or thyroid issues that cause swelling. A keyboard at elbow height and a flat mouse position are small adjustments that make a real difference over time.
The Bottom Line
Carpal tunnel syndrome is one of the most treatable nerve problems there is, but only if you catch it early. That 2 a.m. tingling is your body signaling that something needs attention. The longer you wait, the harder it is to fully reverse the nerve irritation.
If splinting and exercises are not enough, a hands-on evaluation can identify whether joint restrictions in your wrist or cervical spine are adding to the problem.
