Pain is severe during this phase and often unresponsive to traditional [[Pain Medications|pain medications]]. The phase may last 2-4 weeks but the pain may continue. * Chronic [[Infectious Disease|infection]] is characterized by recurrent pain that lasts more than 4 weeks. Besides the pain, patients experience paresthesias, shock-like sensations, and dysesthesias. The pain is disabling and may last 12 months or longer. The involvement of the CNS is not uncommon. since the virus resides in the sensory root ganglia, it can affect any part of the brain causing cranial nerve palsies, muscular weakness, [[Diaphragmatic Breathing Exercises|diaphragmatic]] paralysis, neurogenic bladder, [[Guillain-Barre Syndrome|Guillain Barre syndrome]], and myelitis. In severe cases, patients may develop [[encephalitis]]. '''Image 3:''' Herpes Zoster Rash
