Radicular pain is a type of pain that can occur anywhere in the body and is most commonly caused by intercostal neuralgia and some diseases of the cervical spine such as drop pillow, neck stiffness, and neck pain. When a nerve trunk, nerve root or central nerve lesion is irritated, the pain does not only occur locally to the irritated area, but can extend to the innervation area of the affected sensory nerve, which is called radiating pain. Radicular pain is radiated, and the conduction pain dissipates from the proximal (i.e., near the heart side) to the distal end of the limb, as if the body were running an electric current. Pain in the upper extremity due to neurogenic cervical spondylosis and pain in the lower extremity in lumbar disc herniation and semi-sciatica are typical of radiating pain. The presence of such pain means that the patient’s nerve roots are diseased, and prompt medical consultation is required. Minimally invasive neurointerventional analgesia is a very good solution for this type of pain. For radiological pain, a physical examination of the relevant painful area is needed to find the cause of the radiological pain and to clarify the cause before treatment is done. After the primary disease is cured, not only the pain in the primary organ will disappear, but also the pain in the area where the radioactive pain occurred.
