Numbness in the right thumb, index finger, and middle finger may be caused by various factors. Below are some common causes:

1. Nerve compression: Carpal tunnel syndrome can compress the median nerve at the wrist, causing numbness in the fingers. Prolonged use of computers or mobile phones, or engaging in work requiring repetitive hand movements, may increase the risk of developing this condition.

2. Circulatory problems: Raynaud's disease or Raynaud's phenomenon can reduce blood flow to the fingertips, resulting in a sensation of numbness.

3. Diabetes: High blood sugar levels can damage the nervous system, leading to peripheral neuropathy, which may present as numbness in the fingers and other symptoms.

4. Multiple peripheral neuritis: This condition involves dysfunction of motor, sensory, and autonomic nerves in the extremities and may cause numbness in the fingers.

5. Radiculopathy of the cervical spine: Degenerative changes in the cervical spine may compress nerve roots, leading to local nerve dysfunction and symptoms such as numbness in the hands and feet.

If you experience persistent numbness in your fingers, it is recommended to seek medical evaluation at a reputable hospital promptly.
