Carpal Tunnel Syndrome
Carpal tunnel is median nerve compression at the wrist, often with upstream contributors. We look at the neck, thyroid, blood sugar, hormones, inflammation, and the brain map of the hand.
What you may be noticing
Tingling and numbness in your thumb, index, and middle fingers, often worse at night. You wake and shake your hand to bring it back. Holding a phone, steering wheel, or book makes it worse. Over time grip weakens, and you drop things.
Sudden weakness or numbness on one side of the body, with facial droop or trouble speaking, is a stroke warning. Call 911.
Why it is rarely one thing
The median nerve passes through a tight tunnel in the wrist. When pressure in that tunnel rises, the nerve loses blood flow and signal. Repetitive strain plays a role, yet the wrist is often the last place in a longer story.
A nerve irritated higher up, in the neck or shoulder, may become more vulnerable at the wrist. This double crush idea remains debated in research. Systemic conditions also swell the tissues or sensitize the nerve: hypothyroidism, diabetes and insulin resistance, pregnancy, menopause, rheumatoid arthritis, and fluid retention. Not just a wrist problem, but often a whole-body pattern expressed in the wrist.
This is where upstream sequencing matters. A splint and rest can quiet symptoms, yet if a hypothyroid pattern, high insulin, or a stiff neck keeps loading the nerve, symptoms return. There is also a brain layer: persistent tingling changes how the hand is mapped in the sensory cortex, and refining that map supports grip and dexterity as the nerve settles. For many people conservative care brings meaningful relief, and surgery remains a sound choice when the nerve shows signs of lasting damage.
Patterns we look for
- Cervical spine involvement and nerve root irritation at C6 and C7.
- Thoracic outlet and shoulder mechanics.
- Thyroid function, including hypothyroid tissue swelling.
- Fasting insulin, glucose, and HbA1c.
- Hormone changes in pregnancy and perimenopause.
- Inflammatory and autoimmune markers, such as rheumatoid factor.
- B6 and B12 status. Both deficiency and excess B6 can affect nerves.
- Ergonomics, grip patterns, and sleep posture.
How I evaluate it
The comprehensive functional neurological exam tests sensation, strength, reflexes, nerve tension, and provocative tests at the wrist, elbow, shoulder, and neck to locate where the nerve is being stressed. Two-point discrimination and thumb strength give us a baseline to measure progress. I coordinate nerve conduction studies with your physician when the diagnosis or severity is unclear.
Functional labs may include a full thyroid panel, fasting insulin and glucose, HbA1c, vitamin B12, inflammatory markers, and autoimmune screening when indicated.
How we address it
- Reduce load: ergonomic changes and a neutral wrist splint at night.
- Address upstream mechanics in the neck, shoulder, and thoracic outlet.
- Rebalance thyroid, blood sugar, and hormone contributors, and calm inflammation through nutrition.
- Restore nerve gliding with gentle neural mobilization.
- Refine the brain map of the hand with sensory discrimination and fine motor training.
- Rebuild grip strength with targeted rehabilitation.
- Coordinate with a hand specialist if there is muscle wasting or constant numbness, since surgical release may be the right step.
Your hands carry your work and your life. They deserve care that looks beyond the wrist.
