Definition


Herpes zoster, more commonly known as shingles, is a condition caused by the stimulation of the chickenpox virus (VZV) bringing it out of its latent state that it can occupy for years in a nerve. This condition causes pain localized in one area with vesicles appearing in the form of crusts that fall off after a few days. Intercostal herpes zoster is the most common form, affecting a nerve located in the spinal column involved in the disease reactivation, causing symptoms to manifest in the area innervated by the damaged nerve, on one side of the chest.
