The short explanation
Tingling or numbness in the thumb, index and middle fingers that wakes you at night and improves when you shake your hand is a typical pattern of carpal tunnel syndrome. It happens when a nerve passing through the wrist, called the median nerve, is squeezed. It is common in women, especially in their 40s and 50s, during pregnancy, and with repetitive hand work such as cutting vegetables, typing, tailoring or grinding. Many people improve with simple measures such as wearing a wrist splint at night, avoiding repetitive gripping and bending of the wrist, and hand exercises. A doctor can advise on other treatment if it persists.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Conditions such as an underactive thyroid, diabetes, rheumatoid arthritis and weight gain can make carpal tunnel more likely, so a doctor may check for these.
- Tingling in other fingers, the whole hand, both hands and feet, or with neck pain may have a different cause, such as a nerve in the neck or low vitamin B12.
- A nerve conduction test can confirm the diagnosis and show how much the nerve is affected.
- Night splints are inexpensive and available at most pharmacies and orthopaedic shops; a physiotherapist can show you how to wear one comfortably.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot confirm the cause of your symptoms. That needs an examination and sometimes nerve tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Does this sound like carpal tunnel syndrome?
- Do I need a nerve conduction test?
- Should my thyroid or sugar be checked?
- Would a wrist splint help?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
