The tingling sensation in the arm from time to time should be considered in two ways. On the one hand, it is caused by peripheral neuropathy, such as the presence of diabetes, resulting in peripheral nerve dystrophy, which can lead to numbness in the arm, usually with garter-like changes, and the presence of peripheral neuritis, which can also lead to episodic tingling in the arm. On the other hand, cervical spine disease should be considered, because improper posture will lead to cervical disc herniation after a long time, and when the nerve roots are compressed, numbness and tingling sensation in the arm and hand will occur. It is recommended that the patient visit the hospital for CT, MRI and electromyography of the neck to clarify which is the cause.
