Do I Have Carpal Tunnel? - Symptoms, Causes and Diagnosis Quiz

Do I Have Carpal Tunnel Syndrome? - Symptoms, Causes & Diagnosis

If you're experiencing pain, tingling, or numbness in your hands and wrists, you may be wondering - do I have carpal tunnel syndrome? Carpal tunnel syndrome (CTS) is a common condition caused by compression of the median nerve as it passes through the wrist. Understanding the symptoms, causes, risk factors and diagnosis process can help you determine if carpal tunnel syndrome is the culprit behind your wrist and hand discomfort.

Symptoms of Carpal Tunnel Syndrome

The most common carpal tunnel syndrome symptoms include:

Tingling, itching, burning or numb sensation in the thumb, index, middle and ring fingers
Sharp pain or discomfort in the hand, wrist, or forearm
Weakness or clumsiness in the hand and fingers
Difficulty gripping objects
Fingers feeling swollen even though no swelling is visible

Symptoms often begin gradually and occur frequently at night, disrupting sleep. Some people experience worsening of symptoms during daytime activities involving repetitive hand motions such as typing or gripping a steering wheel.

What Causes Carpal Tunnel Syndrome?

Carpal tunnel syndrome arises when the median nerve gets compressed as it travels through the wrist. The carpal tunnel is a narrow passageway surrounded by bones and ligaments on the palm side of the wrist. When inflammation or swelling occurs in this space, it puts pressure on the median nerve, leading to CTS symptoms.

Common causes and contributing factors include:

Repetitive hand motions that overwork the wrist
Pregnancy due to fluid retention and wrist swelling
Hormonal changes such as menopause
Wrist injury or fracture
Rheumatoid arthritis
Diabetes
Overweight or obesity
Fluid retention due to kidney failure or dialysis
Anatomical factors like having a smaller carpal tunnel area

Risk Factors for Carpal Tunnel

Certain factors can increase your risk of developing carpal tunnel syndrome:

Jobs involving repetitive hand motions - manufacturing, cleaning, cashiering
Computer work involving extensive typing and mouse use
Pregnancy
Being overweight
Being female - women are three times more likely to get CTS
Medical conditions like diabetes, rheumatoid arthritis, underactive thyroid
Older age - peak between 40-60 years old
Genetic predisposition - family history of carpal tunnel

When to See a Doctor

You should make an appointment with your doctor if you experience tingling, numbness or pain in your wrist or hand for more than two weeks. Seek prompt medical care if your symptoms are severe or sudden in onset. Seeing a doctor quickly can help prevent permanent nerve damage. Don't ignore symptoms or assume they will just go away.

How is Carpal Tunnel Syndrome Diagnosed?

To determine whether carpal tunnel syndrome is causing your hand and wrist discomfort, your doctor will perform a physical exam and review your medical history. They may order certain tests to aid in diagnosis.

Physical Exam

During the physical exam your doctor will:

Check for wrist swelling
Test your grip strength by having you grasp their fingers
Assess sensation by touching different parts of your hands with an instrument
Tap over the median nerve to check for tingling (Tinel test)
Bend your wrist gently up and down to reproduce symptoms (Phalen test)

Medical History Review

Your doctor will ask about:

Symptom location, severity, and timing
Which activities make symptoms worse
Sleep disturbances
Medical conditions like diabetes, arthritis
Occupational and recreational hand activities
Prior wrist injuries

Electrodiagnostic Tests

If the initial exam is inconclusive, your doctor may order tests like:

Nerve conduction study - Measures how fast signals travel through the median nerve. Slow speeds indicate nerve compression.
Electromyography - Evaluates muscle electrical activity. Can confirm median nerve dysfunction.

Ultrasound Imaging

Ultrasound uses soundwaves to visualize soft tissues like tendons, nerves and blood vessels in the wrist. This can show carpal tunnel swelling and compression.

MRI Scan

Magnetic resonance imaging provides detailed 3D images of the wrist anatomy. An MRI can reveal compression or irritation of the median nerve.

X-Rays

Plain x-rays are typically normal with carpal tunnel syndrome. But they may be used to rule out issues like arthritis or bone fractures contributing to symptoms.

What is the Carpal Tunnel Screening Quiz?

The Boston Carpal Tunnel Screening Quiz is a simple self-assessment tool that can provide insight into whether your symptoms may be caused by carpal tunnel syndrome. The quiz includes the following questions:

Have you experienced numbness, tingling or weakness in your hand or wrist?
Does this numbness or tingling extend to your fingers?
Have you been waking up at night with symptoms of numbness or tingling?
Do your symptoms improve by shaking or rubbing your hands?
How long have you had these symptoms for?

Based on your answers, the screening tool calculates a score estimating your likelihood of having carpal tunnel syndrome. While not definitive, the quiz can give you a general idea of whether your symptoms match carpal tunnel and if seeing a doctor for evaluation is recommended.

Limitations of the Carpal Tunnel Quiz

Although the carpal tunnel screening quiz can provide some early insight, there are limitations to keep in mind:

It is not a substitute for a doctor's evaluation and diagnostic testing
Many conditions like arthritis or pinched nerves can mimic carpal tunnel syndrome
The quiz cannot officially rule in or rule out carpal tunnel
Symptom severity and duration also impact the likelihood of CTS
A negative quiz does not mean you definitively don't have carpal tunnel

Overall, consider the carpal tunnel quiz as just an initial indicator. Seek medical advice for an accurate diagnosis. Don't rely solely on the quiz to determine if you have carpal tunnel syndrome or not.

Treatment Options for Carpal Tunnel Syndrome

If carpal tunnel syndrome is diagnosed, prompt treatment is recommended to prevent permanent median nerve damage and loss of hand function. Treatment options include:

Wrist Splinting

Wearing a rigid wrist brace or splint, especially at night, can help keep the wrist in a neutral position and reduce compression on the median nerve.

Medications

Oral steroids like prednisone can help reduce nerve inflammation. Non-steroidal anti-inflammatory drugs may also provide relief from CTS pain.

Lifestyle Changes

Avoiding repetitive hand motions, limiting wrist bending, using ergonomic equipment, and treating underlying medical issues can help manage CTS.

Physical Therapy

Stretches, exercises, ultrasound therapy, and massage can improve wrist mobility and circulation.

Carpal Tunnel Surgery

Severely damaged nerves may require surgery to open the ligament compressing the median nerve in the wrist.

Talk to your doctor about the best carpal tunnel treatment options for your individual situation and symptoms.

Preventing Carpal Tunnel Syndrome

You may be able to reduce your carpal tunnel syndrome risk by:

Avoiding overuse of the hands and wrists in activities like typing
Taking regular breaks when performing repetitive motions
Using ergonomic keyboards and equipment
Keeping wrists in a neutral position when gripping or lifting
Doing wrist and hand stretches
Wearing a wrist brace during strenuous tasks
Preventing falls which can cause wrist fractures
Getting conditions like diabetes and rheumatoid arthritis under control
Maintaining a healthy body weight

Implementing preventive strategies before nerve damage occurs gives you the best chance of avoiding carpal tunnel syndrome.

When to Seek Medical Care

Schedule an urgent appointment with your doctor if you have:

Constant numbness, tingling or severe pain in the fingers or hand
Fingers feeling cold, swollen or changing color
Muscle wasting - loss of bulk in the palm or thumb
Weak grip strength making daily activities difficult
Symptoms lasting more than two weeks

Don't ignore persistent wrist discomfort or wait for it to resolve on its own. Prompt carpal tunnel diagnosis and treatment can help prevent lasting median nerve damage and disability.

FAQs

Can carpal tunnel syndrome go away on its own?

In mild cases during early stages, carpal tunnel syndrome symptoms may resolve with rest and wrist splinting. However, the condition often worsens without treatment and can cause permanent nerve damage. Seeking medical advice is recommended.

Which finger is affected by carpal tunnel?

Carpal tunnel syndrome usually affects the thumb, index finger, middle finger and half of the ring finger. The little finger generally does not experience symptoms since it receives nerve supply from a different branch.

Can carpal tunnel affect the whole hand?

Typically carpal tunnel syndrome only affects parts of the hand innervated by the median nerve. However, in severe cases, symptoms like pain, weakness and numbness can spread to affect function of the entire hand.

Is carpal tunnel a disability?

Severe untreated carpal tunnel syndrome can potentially cause permanent disability by damaging the median nerve. However, most cases can be managed with treatment. Talk to your doctor about work restrictions to prevent disability.
