If you’re dealing with carpal tunnel syndrome, the most effective first step is wearing a wrist splint at night and adjusting how you use your hands during the day. Most people with mild to moderate symptoms improve significantly with these conservative measures, and many never need surgery. About 50 out of every 1,000 people in the general population have carpal tunnel syndrome, so you’re far from alone in figuring out what to do about it.
Why Your Hand Hurts
Carpal tunnel syndrome happens when the median nerve gets squeezed as it passes through a narrow channel in your wrist. This channel, the carpal tunnel, is formed by wrist bones on three sides and a thick band of tissue across the top. It can’t stretch or expand. When anything causes swelling inside that space, whether from repetitive motion, fluid retention, or inflammation, the nerve gets compressed.
The compression typically causes tingling and numbness in your thumb, index finger, middle finger, and half of your ring finger. Symptoms often start at night because many people sleep with their wrists bent, which narrows the tunnel further. You might wake up shaking your hand to get feeling back. Over time, you may notice you’re dropping things or struggling with buttons and jar lids.
Start With a Night Splint
A wrist splint worn during sleep is one of the most reliable first treatments. It holds your wrist in a neutral position so the tunnel stays as open as possible while you rest. You can find these at most pharmacies without a prescription. Look for one that keeps your wrist straight, not bent in either direction.
Give it a real trial. Research shows that 12 weeks of consistent night splinting provides meaningful relief not only for mild cases but also for more advanced carpal tunnel syndrome. Some people feel improvement within the first few weeks, but the full benefit takes about three months to develop. If your symptoms are worst during the day, wearing the splint during activities that aggravate your wrist can help too.
Adjust Your Workstation
If you spend hours typing, your wrist position matters more than you might think. Pressure inside the carpal tunnel rises sharply when your wrist extends beyond 30 degrees (bending your hand upward) or deviates toward your thumb side more than 15 degrees. Keeping your wrists as close to neutral as possible while typing measurably reduces that internal pressure.
A few practical changes make a big difference. Reduce the tilt of your keyboard or use a flatter one so your wrists aren’t forced upward. Raise your chair or lower your keyboard so your forearms are roughly parallel to the floor. A split keyboard can help reduce the sideways wrist angle that standard keyboards force, but avoid opening the halves so wide that your wrists angle the other direction. A wrist rest can help during pauses, but avoid resting your wrists on it while actively typing, since that locks them into a bent position.
Nerve Gliding Exercises
Nerve gliding exercises help the median nerve move more freely through the carpal tunnel. They’re simple, take about two minutes, and you do them three times a day. Here’s a common sequence used in clinical settings:
- Step 1: Make a fist with your wrist straight.
- Step 2: Open your hand, straightening all fingers and your thumb.
- Step 3: Bend your wrist back gently while spreading your thumb away from your palm.
- Step 4: Turn your palm to face the ceiling.
- Step 5: With your other hand, gently pull your thumb a little farther from your palm.
Do five repetitions of this sequence, three times per day. The movements should be slow and controlled. You might feel a mild stretch, but stop if you feel sharp pain. These exercises work best alongside splinting and ergonomic changes, not as a standalone fix.
Injections and Medications
Over-the-counter anti-inflammatory medications can take the edge off symptoms, but they don’t address the underlying compression very well. For more targeted relief, a corticosteroid injection directly into the carpal tunnel is significantly more effective. One study comparing steroid injections to anti-inflammatory injections found that corticosteroids provided better pain relief and greater improvement in both symptom severity and hand function at three months.
Steroid injections work best for mild to moderate carpal tunnel syndrome and can buy you weeks to months of relief. Some people use that window to let splinting and ergonomic changes take hold. Others find that symptoms eventually return, at which point surgery becomes a more practical conversation.
When Surgery Makes Sense
Surgery becomes the right choice when conservative treatment hasn’t worked after several months, or when symptoms are severe enough that you’re losing hand function. The clearest warning sign is muscle wasting at the base of your thumb, a visible flattening of the fleshy pad below your thumb. This indicates the nerve has been compressed long enough to cause muscle damage. At that stage, the damage can become permanent if pressure on the nerve isn’t relieved.
Other signs that point toward surgery include constant numbness (not just intermittent tingling), persistent weakness, and clumsiness that interferes with daily tasks. Waiting too long when these symptoms are present risks irreversible nerve damage that surgery can’t fully reverse.
What Surgery Looks Like
Carpal tunnel release surgery cuts the band of tissue forming the roof of the tunnel, permanently relieving pressure on the nerve. There are two approaches: open surgery through a small incision in the palm, and endoscopic surgery through one or two even smaller incisions using a tiny camera.
Both approaches produce equivalent results by six months. The difference is in early recovery. Endoscopic surgery causes less scar tenderness and gets people back to daily activities in about 16 days on average, compared to 20 days for open surgery. In one study, none of the endoscopic patients had scar tenderness at six months, while nearly a third of open surgery patients did.
Recovery is faster than many people expect. Most patients return to desk work or light activities within one to two days. Physically demanding jobs typically require a few weeks. Getting back to sports or heavy lifting takes four to six weeks. Neither approach showed recurrence of symptoms at the six-month mark in comparative studies.
Don’t Wait Too Long
Carpal tunnel syndrome is progressive. Early on, the tingling comes and goes, often only at night. As the condition advances, numbness becomes constant, grip strength drops, and fine motor skills deteriorate. Eventually, the muscles at the base of the thumb waste away visibly, a sign of chronic nerve compression that may not fully recover even after surgery.
The good news is that most people catch it early enough for conservative measures to work. Start with a night splint, fix your workstation, do nerve gliding exercises daily, and reassess after 12 weeks. If you’re not improving, or if you already have weakness or constant numbness, a corticosteroid injection or surgical evaluation is the logical next step.
