Possible causes of numbness in the right index finger include:
1. Nerve compression: At the wrist, compression of the median nerve may cause numbness in the fingers, especially the index finger and thumb. Prolonged repetitive use of the hands, such as typing or playing musical instruments, can also lead to nerve compression.
2. Cervical spondylosis: When degenerative changes or disc herniation occur in the cervical spine, it may compress the nerves of the upper limbs, resulting in symptoms such as numbness and weakness in the fingers.
3. Circulatory disorders: Poor blood circulation, such as atherosclerosis or Raynaud's disease, can affect blood supply to the fingers and cause numbness. In addition, maintaining the same posture for a long time, such as having the arm compressed while sleeping, can temporarily impair circulation and cause finger numbness.
4. Metabolic diseases: Patients with diabetes may experience numbness in the hands and feet, including the index finger, due to nerve damage caused by high blood sugar levels. Abnormal thyroid function can also affect nerve function and cause finger numbness.
