Carpal Tunnel Treatment Guide: Relieve Wrist Pain and Numbness

Overview

Carpal tunnel syndrome is a common condition that causes pain, numbness, and tingling in the hand and arm. It happens when the median nerve—one of the main nerves that runs from the forearm into the hand—is squeezed or pressed as it passes through the carpal tunnel, a narrow passageway in the wrist made of bones and a thick ligament. The condition affects an estimated 4-10 million people in the U.S., and is more common in women and people who perform repetitive hand or wrist movements for work or hobbies.

Signs & Symptoms

Symptoms of carpal tunnel syndrome usually start gradually and may come and go at first, getting worse over time if left untreated. Many people notice their symptoms are most severe at night, sometimes waking them from sleep.

• Numbness or tingling in the thumb, index finger, middle finger, and the thumb side of the ring finger
• Aching or burning pain in the wrist that may spread up the forearm
• Weakness in the hand, making it hard to grip objects, open jars, or button shirts
• A feeling of swelling or puffiness in the fingers even when there is no visible swelling
• Symptoms that get worse with activities that flex the wrist, such as typing, driving, holding a phone, or using hand tools

Causes & Risk Factors

Carpal tunnel syndrome develops when something narrows the carpal tunnel or causes the tissues inside it to swell, putting pressure on the median nerve. The tunnel also contains the tendons that bend the fingers and thumb; inflammation or thickening of these tendons can take up space in the tunnel and compress the nerve.

• Repetitive hand and wrist movements, especially from jobs involving prolonged typing, assembly line work, or using vibrating power tools
• Pregnancy, which can cause fluid retention and swelling in the wrist tissues
• Underlying health conditions including diabetes, rheumatoid arthritis, hypothyroidism, and obesity
• Wrist fractures or dislocations that alter the shape of the carpal tunnel
• Being assigned female at birth, as people assigned female at birth tend to have smaller carpal tunnels than people assigned male at birth

Diagnosis

To diagnose carpal tunnel syndrome, your healthcare provider will first discuss your symptoms, medical history, and daily activities. They may perform a physical exam, including the Tinel sign test (tapping over the median nerve at the wrist to see if it causes tingling in the fingers) and the Phalen maneuver (holding your wrists bent at a 90-degree angle for 60 seconds to see if symptoms appear). They may also order nerve conduction studies or electromyography (EMG) to measure how well the median nerve is functioning and rule out other conditions with similar symptoms.

Treatment & Management

Treatment for carpal tunnel syndrome depends on the severity of your symptoms and how long you have had them. The goal is to relieve pressure on the median nerve, reduce pain and numbness, and prevent permanent nerve damage. Most people start with conservative (non-surgical) treatments, which are effective for mild to moderate cases.

Living With It

Most people with carpal tunnel syndrome see significant improvement with treatment, especially if they start early. To reduce the risk of symptoms returning, make small, sustainable adjustments to your daily routine: keep your wrists in a neutral (straight) position as much as possible, use ergonomic tools like split keyboards or padded mouse pads, and stretch your hands and wrists regularly throughout the day. If your job involves repetitive hand movements, talk to your employer about adjusting your tasks or taking more frequent breaks to reduce strain.
