3. Diagnosing the Cause of Paresthesia

When someone presents with paresthesia, doctors aim to discover the underlying cause of the symptom by requesting a detailed medical history and enquiring into hobbies or occupations that involve repetitive movements. Further tests may include a nerve conduction study, which measures how fast nerve impulses travel, and MRI or CT scans. Sometimes an ultrasound can help view nerve compression or damage in smaller parts of the body, such as the wrists.
