Common causes that may lead to numbness in the fingers:
1. Nerve compression: Excessive force during hand activities or maintaining poor posture for prolonged periods may lead to nerve compression. Conditions such as carpal tunnel syndrome can cause finger numbness.
2. Nerve damage: Injury or disease of the nerves, such as neuritis or diabetic peripheral neuropathy, may also result in finger numbness.
3. Poor blood circulation: Impaired blood circulation can also cause finger numbness, particularly common in cold environments or among individuals with Raynaud's disease.
4. Diabetes: High blood sugar can damage nerves in the body, especially peripheral nerves, leading to numbness in the hands and feet. This symptom is known as diabetic neuropathy.
5. Vitamin deficiency: Particularly a deficiency in vitamin B12 can affect nerve function and cause numbness in the hands and feet.
6. Cervical spondylosis: Herniated cervical discs or bone spur formation may compress nerve roots, leading to finger numbness and pain.
