Carpal Tunnel Syndrome (CTS) is a common hand condition that affects the function of the median nerve as it travels through a narrow passageway in the wrist called the carpal tunnel. The median nerve provides sensation to the thumb, index finger, middle finger, and the thumb side of the ring finger, as well as motor control to some of the muscles at the base of the thumb. When this nerve experiences excessive pressure or compression, you may develop symptoms such as pain, numbness, tingling, and weakness in these areas of the hand.
Why the Median Nerve Matters
The median nerve is one of the key nerves that allow your hand to feel and move. It starts from a network of nerves in the neck (the brachial plexus), travels down your arm, and then passes through the carpal tunnel in your wrist. If any factors reduce the space in this tunnel or increase pressure on the nerve, you’ll likely experience discomfort or even functional limitations in your hand. The severity can range from mild inconvenience—like a “pins and needles” sensation when typing—to severe pain and muscle atrophy if left untreated for a long time.
Prevalence and Who’s at Risk
Carpal Tunnel Syndrome affects millions of people worldwide. Studies show that women are about three times more likely than men to develop CTS. The reason for this gender disparity isn’t fully understood, but it may be related to hormonal factors, differences in wrist anatomy, or occupational hazards. CTS often develops between the ages of 30 and 60, though it can appear at any age, especially if there’s significant repetitive strain or underlying health conditions.
At TMSC, our board-certified plastic surgeons specialize in safe, effective treatments for carpal tunnel syndrome. Whether your symptoms have just begun or you’ve been coping with hand discomfort for years, we’re here to restore function, reduce pain, and help you regain confidence in daily tasks.
An interactive guide to help you identify symptoms early and understand the progression of carpal tunnel syndrome.
Identifying the signs of Carpal Tunnel Syndrome early can make a big difference in preventing further nerve damage. This condition occurs when the median nerve, which runs from your forearm into your hand, becomes compressed at the wrist.
The carpal tunnel is a narrow passageway surrounded by bones and ligaments on the palm side of your hand. When the tunnel narrows or tissues surrounding the flexor tendons swell, it puts pressure on the median nerve.
If symptoms persist or worsen over time, seek professional evaluation. Early intervention can help prevent permanent nerve damage and maintain hand functionality.

Visible hand deformity
Correct! Nighttime tingling and numbness are often the earliest signs of carpal tunnel syndrome.
Carpal Tunnel Syndrome Symptoms
Identifying the signs of Carpal Tunnel Syndrome early can make a big difference in preventing further nerve damage. Here are some hallmark symptoms:
Pain, Numbness, and Tingling
Typically felt in the thumb, index finger, middle finger, and the thumb side of the ring finger.
This discomfort can feel like a “pins and needles” sensation or an “electric shock” that might even wake you up at night.
Hand Weakness
A noticeable decrease in grip strength can make it tough to hold objects like mugs, phones, or pens.
You might find yourself dropping things more frequently or struggling to twist jar lids.
Difficulty with Fine Motor Skills
Activities requiring dexterity—like buttoning shirts, typing, or playing a musical instrument—might become more challenging.
Shock-Like Sensations
Some people describe sudden, sharp, shock-like pains shooting into the fingers or traveling up the forearm.
Muscle Cramping
Occasional cramps or spasms in the muscles of the hands, particularly if the condition is more advanced.
Tingling That Extends Up the Arm
Symptoms can sometimes radiate upward from the wrist into the forearm and, in severe cases, even toward the shoulder.
If these symptoms persist or worsen over time, it’s crucial to seek a professional evaluation. Early intervention can help prevent permanent nerve damage and maintain your hand’s functionality.
Causes of Carpal Tunnel Syndrome
The carpal tunnel is a rigid, narrow passage on the palm side of your wrist. It’s formed by carpal bones on the bottom and sides, and by a tough band of connective tissue (the transverse carpal ligament) on the top. This tight space houses the median nerve and nine flexor tendons that help flex your fingers.
Carpal Tunnel Syndrome occurs when the space in this tunnel decreases or when swelling around the tendons increases enough to compress the median nerve. Here are some of the most common contributors:
Repetitive Hand Movements
Typing, using a mouse, or assembly-line work can put repetitive strain on the wrist.
Improper wrist positioning—like resting your wrists on a desk or keyboard edge—further contributes to increased pressure on the nerve.
Medical Conditions
Hypothyroidism, obesity, rheumatoid arthritis, and diabetes are known to increase the likelihood of CTS.
These conditions can lead to fluid retention or swelling that narrows the available space in the carpal tunnel.
Pregnancy
Hormonal changes during pregnancy can cause fluid retention, leading to swelling.
This swelling often subsides after childbirth, resolving mild to moderate CTS symptoms.
Wrist Anatomy
Some people are simply born with smaller carpal tunnels, making them more susceptible to nerve compression.
Previous wrist fractures or dislocations can also alter the space in the tunnel, increasing vulnerability.
Inflammation and Edema
Certain inflammatory conditions can thicken the tissues or tendons in the wrist.
Water retention or edema for other reasons (e.g., kidney issues, diet, or medications) can also contribute.
Diagnosis of Carpal Tunnel Syndrome
1. Physical Examination
A healthcare provider will typically start by evaluating your hand strength, sensation, and range of motion. Maneuvers like Tinel’s sign (tapping over the median nerve) or Phalen’s test (flexing the wrists for about 60 seconds) can provoke or worsen symptoms, aiding in diagnosis.
2. Medical History
Your doctor will discuss your symptoms, daily activities, occupational hazards, and any pre-existing conditions. This information helps pinpoint contributing factors—such as prolonged computer use or a chronic condition like diabetes.
3. Nerve Conduction Studies
To confirm the diagnosis, specialists may order a nerve conduction study or electromyography (EMG). These tests:
Measure how quickly the median nerve transmits electrical signals.
Assess the severity of nerve compression by detecting slowed transmission or abnormal muscle response.
These diagnostic tools are crucial for determining treatment as well, since they offer insight into how advanced the compression has become and whether surgery might be necessary.
Non-Surgical Treatments
Before considering surgery, many patients try non-surgical interventions to relieve symptoms. These methods can be highly effective in mild to moderate cases of Carpal Tunnel Syndrome:
Wrist Splinting
Wearing a wrist brace (particularly at night) prevents you from bending your wrist while sleeping, relieving pressure on the nerve.
Splints are also useful during repetitive tasks, such as typing.
Anti-inflammatory Medications
Over-the-counter (OTC) or prescription non-steroidal anti-inflammatory drugs (NSAIDs) can reduce swelling around the tendons.
Though NSAIDs may ease discomfort, they don’t always address the root cause.
Steroid Injections
A corticosteroid injection into the carpal tunnel region can provide short-term relief by reducing inflammation.
Relief can last for several weeks or months, but repeated injections may be needed.
Ergonomic Modifications
Adjusting your workstation to ensure neutral wrist positioning while typing or using a mouse can make a significant impact.
Ergonomic keyboards, padded wrist supports, and proper desk height reduce tension on the median nerve.
Lifestyle Changes
Taking regular breaks during repetitive activities, stretching your hands, and using proper lifting techniques can help.
Maintaining a healthy weight and managing conditions like hypothyroidism or diabetes can also lower CTS risk.
Physical or Occupational Therapy
Specific exercises and stretches under the guidance of a therapist can strengthen the wrist muscles and improve flexibility.
Therapists can also train patients to reduce strain during daily tasks or work-related activities.
In many cases, these interventions can delay or even prevent the need for surgery, especially if treatment begins when symptoms first appear.
How Much Does Carpal Tunnel Syndrome Treatment Cost?
In Ontario, the Ontario Health Insurance Plan (OHIP) generally covers the cost of surgical treatment for Carpal Tunnel Syndrome when deemed medically necessary. This typically includes:
Surgical fees
Hospital or surgical facility charges
Anesthesia (if required)
However, your specific coverage may vary depending on the severity of your CTS and the type of procedure chosen. For instance, endoscopic release may or may not be fully covered, depending on factors like the hospital or facility policies.
What’s Not Covered?
Non-surgical treatments and additional therapies aren’t always covered by OHIP. These may include:
Physical therapy (depending on the setting)
Certain medications
Specialized ergonomic equipment
Post-surgical splints if required beyond basic medical aids
Because insurance coverage can differ, we encourage you to book a free consultation at our Toronto or Oakville clinics. Our team can provide a personalized estimate based on your unique medical needs and guide you on what’s likely to be covered under OHIP.
Carpal Tunnel Syndrome Surgery in Toronto and Oakville
When non-surgical methods aren’t enough—or if your condition is particularly severe—surgery may be the most effective way to relieve pressure on the median nerve. At TMSC, we offer carpal tunnel release surgery, a proven procedure that can dramatically improve symptoms and restore hand functionality.
Open Carpal Tunnel Release
Incision
An open carpal tunnel release involves making a small (1–2 inch) incision along the palm side of your wrist.
This allows direct access to the transverse carpal ligament, the structure that forms the “roof” of the tunnel.
Ligament Cutting
Your surgeon will cut (release) the ligament to enlarge the carpal tunnel space.
This relieves compression on the median nerve, significantly reducing the numbness and pain.
Closure
The incision is then closed with stitches, and a bandage or dressing is applied.
Depending on the patient, sometimes a splint or brace is recommended during the early phase of healing.
What to Expect During Surgery
Local Anesthesia: Often, only local anesthesia is required, which numbs your wrist and hand while you remain awake but comfortable.
Short Procedure: The surgery itself usually takes less than 30 minutes.
Same-Day Discharge: In most cases, patients can go home the same day, as carpal tunnel release is an outpatient procedure.
Endoscopic Carpal Tunnel Release
Though not mentioned in every clinic’s standard practices, some surgeons also perform an endoscopic release using a smaller incision and a thin camera. This can reduce scarring and potentially lead to faster recovery, though not all cases are suitable for this approach. Your surgeon will discuss whether it’s an appropriate option for you.
Recovery Process After Carpal Tunnel Surgery
Immediate Post-Operative Care
You’ll likely experience some soreness in your palm and wrist for a few days.
Keeping your hand elevated can help minimize swelling.
You may be advised to avoid heavy gripping or lifting for a set period—often 2 to 4 weeks.
Physical Therapy and Exercises
Hand and wrist exercises can speed up your recovery. These might include gentle range-of-motion exercises and grip-strength exercises.
A hand therapist or physical therapist can tailor a program to your specific needs, ensuring you regain strength and coordination as efficiently as possible.
Returning to Work and Activities
Many people can return to light activities or desk work within 1 to 2 weeks of surgery, especially if the job doesn’t require heavy lifting or repetitive wrist motions.
Full recovery, particularly for manual labor jobs or high-intensity sports, can take several weeks to a few months.
Follow your surgeon’s guidelines to avoid re-injury and allow the ligament time to heal properly.
Carpal Tunnel Syndrome FAQ
Frequently Asked Questions
The earliest indicators often include tingling or numbness in the thumb, index, and middle fingers. You may notice a burning or pins and needles sensation that can extend to the forearm.
These symptoms sometimes worsen at night, disturbing your sleep. Many patients also report weakness in grip strength and difficulty with fine motor tasks like buttoning clothes or picking up small objects.
Diagnosis usually starts with a physical examination to evaluate sensation, strength, and any provocative tests (like Tinel's or Phalen's test). Further confirmation might involve nerve conduction studies or electromyography (EMG) to gauge the severity of nerve compression.
Your doctor may also review your medical history and discuss your daily activities to identify potential risk factors contributing to the condition.
Mild to moderate cases can often be managed or improved with non-surgical treatments like wrist splints, anti-inflammatory medications, and ergonomic adjustments. However, if these methods don't provide relief or if nerve compression is severe, surgery might be necessary.
Early intervention is key - the sooner treatment begins, the better the chances of avoiding surgical intervention.
Recovery timelines vary per individual. Some notice significant improvement of symptoms within a few days to a few weeks post-surgery, while full grip strength and flexibility can take several months.
Following your surgeon's post-operative instructions is key. Most patients can return to light activities within 2-6 weeks, with full recovery typically occurring within 3-6 months.
Many patients benefit from physical therapy or occupational therapy to expedite healing, strengthen the muscles in the hand and wrist, and fine-tune their daily activities to prevent recurrence.
Therapy typically begins 1-2 weeks after surgery and focuses on reducing scar tissue, improving range of motion, and gradually building strength back to pre-surgery levels.
Yes, there is a possibility of recurrence, particularly if lifestyle factors (e.g., repetitive strain, poor wrist ergonomics) aren't modified. However, successful surgery and proper aftercare greatly reduce the likelihood of symptoms returning.
The recurrence rate is relatively low (less than 5-10%) when patients follow proper post-treatment care and make necessary lifestyle adjustments.
Yes, OHIP generally covers surgery for carpal tunnel syndrome when deemed medically necessary. Non-surgical options like splints or therapy may have separate costs, so consult our clinic or your insurance provider for specifics.
Additional coverage for physiotherapy, occupational therapy, and medical devices may be available through extended health plans or workplace benefits.
Prevention strategies include:
Maintain good posture and a neutral wrist position during work
Use ergonomic equipment such as supportive wrist pads and specially designed keyboards
Take regular breaks from repetitive tasks to stretch and flex your wrists
Perform hand and wrist exercises that improve flexibility and blood circulation
Maintain a healthy weight and manage underlying conditions like diabetes or arthritis
Avoid excessive force when gripping objects and vary your hand positions throughout the day
During flare-ups or active symptoms, you should limit or modify activities that involve:
Repetitive wrist motions like excessive typing or mouse use
Forceful gripping of tools, steering wheels, or other objects
Prolonged flexed wrist positions such as sleeping with bent wrists
Vibrating tools like power drills or chainsaws
Activities that require pinching motions for extended periods
Work with your healthcare provider to develop strategies for modifying necessary activities rather than avoiding them completely.
Several home remedies can provide temporary relief:
Ice therapy for 15-20 minutes to reduce inflammation during acute flare-ups
Gentle stretching exercises for the wrists, hands, and fingers
Wrist splints worn at night to maintain neutral wrist position
Anti-inflammatory medications like ibuprofen or naproxen (consult your doctor first)
Ergonomic adjustments to your workspace and daily activities
Taking frequent breaks from repetitive activities
While these can provide temporary relief, it's important to consult with a healthcare professional for proper diagnosis and treatment planning.
You should seek medical attention if you experience:
Persistent numbness or tingling that doesn't improve with rest
Weakness in your hand or difficulty gripping objects
Pain that interferes with sleep or daily activities
Symptoms that worsen over time despite self-care measures
Loss of sensation in your fingers or thumb
Symptoms that affect both hands simultaneously
Early intervention often leads to better outcomes and may prevent the need for surgical treatment.
Carpal tunnel syndrome specifically affects the median nerve and typically causes symptoms in the thumb, index, middle, and half of the ring finger. Other conditions include:
Cubital tunnel syndrome - affects the ulnar nerve, causing numbness in the pinky and ring finger
Trigger finger - causes fingers to lock or catch when bending
De Quervain's tenosynovitis - affects tendons on the thumb side of the wrist
