1. Carpal Tunnel Syndrome
Pressure on the median nerve from repetitive motion or bent wrists can cause tingling in the thumb, index, and middle fingers. Wearing a wrist brace may help.
2. Ulnar Nerve Compression
Sleeping with bent arms or arms tucked under your body can compress the ulnar nerve near the elbow, leading to numbness in the pinky and ring fingers.
Keeping the arm straight with pillows can reduce symptoms.
3. Vitamin B12 Deficiency
Low B12 levels may damage nerves, causing pins and needles. Vegans and vegetarians are more prone.
If you’re also tired or weak, consider a blood test.
4. Diabetic Neuropathy
High blood sugar harms peripheral nerves over time.
For people with diabetes or prediabetes, nighttime numbness can be an early warning sign.
5. Cervical Disc Problem
