That strange pins-and-needles sensation in your fingers can be uncomfortable. Sometimes it happens after sleeping on your arm, but frequent tingling may indicate that a nerve or another part of your body needs attention.
1. Sleeping in an awkward position: Pressure on the arm or wrist can temporarily affect nerves and cause tingling.
2. Carpal tunnel syndrome: This happens when the median nerve is compressed at the wrist. It commonly affects the thumb, index and middle fingers.
3. Vitamin B12 deficiency: Low vitamin B12 can affect nerve health, causing tingling, numbness and sometimes balance problems.
4. Diabetes: Persistently high blood sugar can damage nerves over time, sometimes affecting the hands and feet.
5. Neck problems: A compressed nerve in the neck can produce pain, numbness or tingling that travels into the fingers.
6. Repetitive hand movements: Repeated wrist movements during work or certain activities can contribute to nerve irritation.
7. Some medications: Certain medicines can cause nerve-related side effects. Never stop a prescribed medicine without speaking to your healthcare professional.
If tingling continues, becomes worse or affects your grip, arrange a medical assessment.
Sudden numbness or weakness on one side of the body, particularly with facial drooping or speech difficulty, may indicate a stroke. Seek emergency medical help immediately.
