Depending upon the location of the symptoms occurring, a doctor may recommend some tests to determine the overlying cause of the hypoesthesia. These tests include imaging computerized axial tomography (CT) and magnetic resonance imaging (MRI) scans, nerve conduction studies to measure electrical impulses passing through the nerves in search of damage to the nerves, and various reflex tests.
The choice of diagnostic procedures depends on the location of the symptoms. A healthcare professional might recommend a range of tests, including CT and MRI scans, nerve conduction studies to evaluate nerve function, and reflex tests to pinpoint the underlying cause of hypoesthesia.
