Understanding Carpal Tunnel Syndrome: Causes, Symptoms & Treatment Options
Updated: 1 day ago
DOXA Specialist Clinic | Workspace Ergonomics series
Does tingling in your hand wake you at night? Are you dropping objects or struggling with buttons? Carpal tunnel syndrome may be one explanation. Understanding your symptoms can help you seek the right assessment and make informed choices about treatment.
At DOXA Specialist Clinic in Saint Lucia, care begins with identifying the cause of your symptoms and discussing a plan that suits your hand function, daily activities and needs.
What is Carpal Tunnel Syndrome (CTS)?
Carpal Tunnel Syndrome (CTS) is a common nerve condition caused by the compression of the median nerve, which runs from the forearm through a narrow passageway in the wrist called the carpal tunnel, and into the hand. This nerve controls sensation and muscle movement in parts of the hand, especially the thumb and first three fingers.
When the space within the carpal tunnel becomes restricted—due to swelling, repetitive motion, or anatomical factors—it can put pressure on the median nerve, leading to discomfort and reduced hand function.
Common Symptoms of Carpal Tunnel Syndrome
If you’ve noticed unusual sensations in your hand or wrist, especially during work or at night, you could be experiencing early signs of CTS. The most common symptoms include:
Numbness or tingling in the thumb, index, middle, and part of the ring finger.
A weak grip, making it harder to hold objects or perform fine motor tasks.
Symptoms worsening at night, often waking you from sleep and prompting you to "shake out" your hands.
Left untreated, CTS can lead to muscle wasting at the base of the thumb, long-term nerve damage, and chronic pain.
What increases the risk?
CTS usually reflects several contributing factors. These include inherited anatomy, pregnancy-related swelling, diabetes, rheumatoid arthritis, thyroid disorders and previous wrist injury. Forceful gripping, vibrating tools and repeated or sustained wrist bending may also be relevant. AAOS patient information and NHS guidance
Does typing cause carpal tunnel syndrome?
Typing should not be presented as a proven cause. The 2024 American Academy of Orthopaedic Surgeons (AAOS) guideline gives a consensus opinion of no association with high keyboard use, while acknowledging very low-quality evidence. This is not strong proof that a relationship is impossible. AAOS guideline
Discomfort during computer work still matters. A task that brings on symptoms does not, by itself, establish what caused the underlying condition. Discuss both your work habits and your wider health history during assessment.
Diagnosis: How We Identify CTS
Assessment starts with your symptoms and a hand examination. AAOS supports the CTS-6 clinical assessment in place of routine ultrasound or nerve-conduction/EMG testing. Additional tests can be selected when needed; MRI is not recommended to diagnose CTS. AAOS guideline
Tell your clinician which fingers are affected, when symptoms occur, whether sleep is disturbed, and whether you have noticed weakness. Bringing this information is more useful than assuming every painful or tingling hand has the same diagnosis.
Treatment Options for Carpal Tunnel Syndrome
Managing CTS effectively depends on its severity and the underlying cause. Here’s how we approach it:
1. Wrist Splinting
Wearing a neutral wrist splint, especially at night, can relieve pressure on the median nerve and prevent symptom flare-ups. This is often the first line of treatment for mild to moderate CTS.
2. Anti-Inflammatory Medications
Non-steroidal anti-inflammatory drugs (NSAIDs) can reduce swelling and discomfort. In some cases, corticosteroid injections may be recommended for short-term relief.
3. Physiotherapy
Our physiotherapists at Doxa Specialist Clinic offer targeted exercises to stretch and strengthen the wrist and forearm muscles. Manual therapy, nerve gliding techniques, and ergonomic adjustments are also used to reduce pressure on the nerve.
4. Surgical Intervention
For patients with severe or persistent CTS not responding to conservative treatment, a minor outpatient surgery called carpal tunnel release may be recommended. This procedure involves cutting the ligament pressing on the nerve to relieve pressure and restore normal function.
Our clinic provides personalized post-op rehabilitation plans to ensure a quick and smooth recovery.
When should you seek help?
Arrange an assessment if symptoms persist, worsen, disturb sleep or interfere with daily tasks. Seek prompt assessment for constant numbness, increasing weakness, repeated dropping of objects or visible muscle loss. NHS guidance and AAOS patient information
Working more comfortably at your computer
Use these adjustments as starting points for comfort:
· Keep the keyboard close and just below elbow height, with relaxed shoulders.
· Position the mouse close to the keyboard to reduce reaching.
· Keep the screen directly in front of you, with its top around eye level.
· For prolonged laptop work, consider a separate keyboard and mouse so the screen can be raised.
· Build short breaks and changes of activity into the day so you can move and change position.
An ergonomic setup is a useful part of working comfortably. It does not establish a diagnosis or guarantee that CTS will resolve.
