First, your doctor will perform a physical exam and ask about your medical history. If he or she still can’t tell whether your symptoms are caused by peripheral neuropathy, there are other tests to perform.
Blood tests can measure vitamin and blood sugar levels and determine whether your thyroid is functioning correctly.
Your doctor may also order a computed tomography (CT) scan or magnetic resonance imaging (MRI) to see if anything is pressing on a nerve, such as a herniated disk or a tumor.
