Have you ever woken up in the middle of the night because your fingers were tingling or felt as though they had fallen asleep? This sensation is often temporary, but repeated numbness may be linked to an underlying problem.
1. Sleeping on your arm: Putting pressure on your arm or wrist while sleeping can temporarily compress nerves and cause tingling.
2. Carpal tunnel syndrome: This condition occurs when the median nerve is compressed at the wrist. It can cause numbness, tingling and pain, especially in the thumb, index and middle fingers.
3. Diabetes-related nerve damage: Persistently high blood sugar can damage nerves over time, sometimes causing tingling or numbness in the hands and feet.
4. Neck problems: Pressure on nerves in the neck can cause symptoms that travel down the arm into the fingers.
5. Vitamin B12 deficiency: Vitamin B12 is important for healthy nerve function. A deficiency can sometimes cause numbness, tingling and balance problems.
6. Certain nerve conditions: Other medical conditions can affect the nerves and cause recurring sensations in the hands.
If the numbness keeps returning, lasts a long time or affects your ability to hold objects, arrange a medical assessment.
Sudden numbness affecting one side of the body, particularly with facial drooping, weakness or difficulty speaking, may be a stroke. Seek emergency medical help immediately.
Occasional tingling may be harmless, but repeated symptoms deserve attention.
