Hand Numbness at Night: Is It Carpal Tunnel? A Bedford Hand Surgeon Explains
Waking up at night shaking your hand to “wake it up”? Nighttime hand numbness is one of the most common signs of carpal tunnel syndrome. Dr. Steven L. Brown, a fellowship-trained hand surgeon in Bedford, NH, explains the causes, warning signs, and treatment options, from night splints to outpatient carpal tunnel release.
If you wake up at 2 a.m. shaking your hand to “wake it up,” you’re not alone. Hand numbness at night is one of the most common reasons patients across Bedford, Manchester, and Nashua come to see Dr. Steven L. Brown, a board-certified plastic surgeon with fellowship training in hand and microsurgery. In many cases, the cause is carpal tunnel syndrome, a very treatable condition. When it’s caught early, simple changes can often relieve it without surgery.
Here’s what causes nighttime hand numbness, how to tell if it’s carpal tunnel, and when it’s time to see a hand surgeon in New Hampshire.
Why Do My Hands Go Numb at Night?
The median nerve runs from your forearm into your hand through a narrow passage in the wrist called the carpal tunnel. It supplies feeling to your thumb, index, middle, and part of your ring finger.
At night, several things can squeeze that nerve:
- Wrist position. Many people sleep with their wrists curled under or bent. Bending the wrist narrows the carpal tunnel and raises the pressure on the nerve.
- Fluid shifts. When you lie down, fluid redistributes in the body. A small amount of swelling in a tight space can be enough to cause symptoms.
- Repetitive daytime use. Typing, tools, gripping, and vibration during the day can irritate the tendons that share the tunnel with the nerve.
Other conditions can also cause numb hands, including nerve compression at the elbow (cubital tunnel syndrome), a pinched nerve in the neck, diabetes, and thyroid conditions. That’s why an accurate diagnosis matters.
Carpal Tunnel Symptoms to Watch For
Carpal tunnel symptoms often begin gradually. Common signs include:
- Numbness or tingling in the thumb, index, and middle fingers, while the pinky is usually spared
- Waking at night with “pins and needles,” and relief from shaking or flicking the hand
- Numbness while holding a phone, steering wheel, or book
- Dropping things or trouble with buttons, jewelry clasps, or small objects
- Aching that can travel up the forearm
- In advanced cases, weakness or visible thinning of the muscle at the base of the thumb
A quick self-check: If your numbness involves the pinky finger, the source may be the ulnar nerve rather than the median nerve. A hand surgeon can tell the difference with a focused exam.
When Is Nighttime Numbness Serious?
Occasional tingling after sleeping on your arm usually isn’t a concern. Make an appointment with a hand specialist if:
- Numbness wakes you up several nights a week
- Symptoms last longer than a few weeks or keep getting worse
- You notice weakness, clumsiness, or are dropping objects
- Numbness becomes constant instead of coming and going
- The muscle at the base of your thumb looks flatter than on the other hand
Long-standing, severe compression can cause permanent nerve damage. Early evaluation gives you the most treatment options and the best chance of a full recovery.
How Carpal Tunnel Syndrome Is Diagnosed
At your consultation in our Bedford office, Dr. Brown will:
- Review your symptoms and history, including your work, hobbies, and any medical conditions.
- Perform a hand exam, testing sensation, strength, and specific provocative tests that reproduce symptoms.
- Order nerve testing when appropriate. A nerve conduction study (EMG/NCS) measures how well the median nerve is working and helps grade severity.
Because Dr. Brown is a plastic surgeon with fellowship training in hand and microvascular surgery, his evaluation focuses on nerves, tendons, and soft tissue, which is exactly where carpal tunnel syndrome happens.
Non-Surgical Treatment Options
For mild to moderate carpal tunnel syndrome, conservative care is often the first step:
- Night splinting. A brace that keeps your wrist straight while you sleep is one of the most effective first-line treatments for nighttime symptoms.
- Activity changes. Adjusting keyboard height, taking breaks, and reducing forceful gripping can lower pressure on the nerve.
- Corticosteroid injection. An injection into the carpal tunnel can reduce inflammation and give temporary relief. It can also help confirm the diagnosis.
- Managing contributing conditions, such as diabetes or thyroid disease, with your primary care physician.
When Carpal Tunnel Surgery Makes Sense
If symptoms keep coming back despite splinting, or if testing shows moderate to severe nerve compression, carpal tunnel release surgery is often recommended. The procedure releases the ligament that forms the roof of the carpal tunnel. That creates more space and relieves pressure on the nerve.
What patients in southern New Hampshire should know:
- It’s an outpatient procedure. Dr. Brown performs most hand procedures at the Bedford Ambulatory Surgical Center, where he serves as Medical Director, so you go home the same day.
- Nighttime symptoms often improve quickly. Many patients notice better sleep soon after surgery. Numbness from long-standing compression can take longer to recover.
- It’s typically covered by insurance. Carpal tunnel release is usually considered medically necessary. Our team will help with prior authorization if your plan requires it.

Tips to Reduce Hand Numbness at Night Starting Tonight
While you wait for your appointment, these steps may help:
- Wear an over-the-counter wrist splint in a neutral position while you sleep
- Avoid sleeping with your hands tucked under your pillow or curled toward your chest
- Take regular breaks from typing and phone use during the day
- Keep your wrists straight when you type, with your keyboard at elbow height
- Shake out or gently stretch your hands when tingling starts
If these steps don’t help within a few weeks, it’s time for a professional evaluation.
Frequently Asked Questions
Can carpal tunnel go away on its own?
Mild cases linked to a temporary cause, such as pregnancy or a short-term activity, may improve. Persistent or worsening symptoms usually need treatment to prevent lasting nerve damage.
Is hand numbness at night always carpal tunnel?
No. Ulnar nerve compression at the elbow, a pinched nerve in the neck, and certain medical conditions can also cause numbness. A hand surgeon can pinpoint the source.
How long is recovery after carpal tunnel surgery?
Most patients return to light activities within days and gradually resume normal use over several weeks. Recovery depends on the severity of nerve compression and the demands of your job.
