Shingles What it looks like : Also known as herpes zoster, shingles is a blistering rash. It often appears in a stripe or in the top quadrant of the head, but only on one side of the body.
Shingles, also known as herpes zoster or zona, [6] is a viral disease characterized by a painful skin rash with blisters in a localized area. [2] [7] Typically the rash occurs in a single, wide mark either on the left or right side of the body or face. [1]
Shingles is caused by varicella zoster virus (VZV), an alpha-herpesvirus. Initial VZV infection usually occurs in childhood causing chickenpox . After this resolves, the virus is not eliminated from the body, but remains latent in the nerve cell bodies of the dorsal root or trigeminal ganglia , without causing symptoms.
A dermatome is an area of skin supplied by sensory neurons that arise from a spinal nerve ganglion. Symptoms that follow a dermatome (e.g. like pain or a rash) may indicate a pathology that involves the related nerve root. Examples include somatic dysfunction of the spine or viral infection.

Similar to the herpes simplex viruses, after primary infection with VZV (chickenpox), the virus lies dormant in neurons, including the cranial nerve ganglia, dorsal root ganglia, and autonomic ganglia. Many years after the person has recovered from initial chickenpox infection, VZV can reactivate to cause shingles. [4]
Atopic dermatitis (AD), also known as atopic eczema, is a long-term type of inflammation of the skin. [2] Atopic dermatitis is also often called simply eczema but the same term is also used to refer to dermatitis, the larger group of skin conditions. [2] [5] Atopic dermatitis results in itchy, red, swollen, and cracked skin. [2]
Postherpetic neuralgia (PHN) is neuropathic pain that occurs due to damage to a peripheral nerve caused by the reactivation of the varicella zoster virus (herpes zoster, also known as shingles). PHN is defined as pain in a dermatomal distribution that lasts for at least 90 days after an outbreak of herpes zoster. [ 1 ]
