Carpal Tunnel Syndrome and Nerve Disorder Evaluation

What carpal tunnel syndrome is

Carpal tunnel syndrome occurs when the median nerve is compressed as it passes through the wrist. Because that nerve supplies sensation to the thumb, index, middle, and part of the ring finger, symptoms follow a characteristic pattern.

• Numbness and tingling in the thumb, index, and middle fingers
• Symptoms that wake you at night
• Relief from shaking or flicking the hand
• Symptoms while driving, holding a phone, or typing
• Aching in the wrist or forearm
• Dropping objects or difficulty with buttons and jar lids
• Thinning of the muscle at the base of the thumb in advanced cases

Peripheral neuropathy

Peripheral neuropathy refers to damage or dysfunction of the peripheral nerves, commonly causing burning pain, numbness, tingling, or imbalance that begins in the feet. Evaluation includes looking for contributing causes such as diabetes, vitamin deficiencies, thyroid disease, medications, alcohol use, and inflammatory conditions.

Treatment

Mild and moderate carpal tunnel syndrome often responds to conservative measures such as wrist splinting — particularly at night — activity and ergonomic modification, and treatment of contributing medical conditions. Persistent symptoms, significant weakness, or severe findings on testing prompt referral for a surgical opinion.

Frequently asked questions

Can a neurologist evaluate carpal tunnel syndrome?

Yes. Carpal tunnel syndrome is a nerve problem, and neurological evaluation with EMG and nerve conduction testing can confirm whether the median nerve is affected at the wrist and how severe the compression is.

Why do my hands go numb at night?

Night symptoms are typical of carpal tunnel syndrome because wrist position during sleep increases pressure on the median nerve. Other nerve problems and neuropathy can produce similar symptoms, which is why testing is useful.

What is ulnar neuropathy?

Ulnar neuropathy is irritation or compression of the ulnar nerve, most often at the elbow. It commonly causes numbness or tingling in the small and ring fingers and, over time, weakness of grip and hand coordination.

Do I need surgery for carpal tunnel syndrome?

Not always. Management depends on severity and testing results and may include activity modification, wrist splinting, treatment of contributing conditions, or referral for a surgical opinion when appropriate.
