Pain is the preliminary sign of herpes zoster. Few days later, skin rashes develop only on one side of the body affecting one or more skin dermatomes. In many cases, the rash develops on the left or right side of the torso. However, many individuals may develop the rash on one side of the neck or face or around the eyes. In addition to these, other signs and symptoms of herpes zoster include the following [7]:

• Burning accompanied by tingling sensation in the affected area
• Pruritic rashes 
• Skin rash with blisters that break and develop crust
• Individuals with herpes zoster also suffer from fever, fatigue and headache

• Pain

  Sometimes there is pain without rash—herpes zoster "sine eruptione"—or rash without pain, most often in children. Pain and general symptoms subside gradually as the eruption disappears. [dermnetnz.org]

  Is shingles painful? Some people with shingles only experience mild symptoms, such as tingling or itchy skin. For others, it can be very painful. Even a gentle breeze can cause pain. Some people experience intense pain without developing a rash. [healthline.com]

  Types of pain experienced by people with postherpetic neuralgia include: constant or intermittent burning, aching, throbbing, stabbing, or shooting pain allodynia – where you feel pain from something that should not be painful, such as changes in temperature [nhsinform.scot]

  Measures of pain burden that reflect the area under the pain intensity—pain duration curve [ 9, 20 ] were calculated by multiplying the pain intensity composite scores and the sensory and affective pain scores by the estimated number of days with pain [dx.doi.org]

• Hyperesthesia

  This pattern is called zoster sine herpete (zoster without rash) and affected patients have severe pain of abrupt onset and hyperesthesia over a specific dermatome. [ncbi.nlm.nih.gov]

  It is known that, with previous varicella infection, the virus lies dormant in the dorsal root ganglia and, on reactivation, results in the commonly described sensory symptoms of hyperesthesia or paraesthesia in the affected dermatome [1]. [hindawi.com]

  Patients will typically experience 1-2 days of pain, itching, and hyperesthesia before the skin lesions are noticed.[3] [1] Etiology/Causes Herpes Zoster is caused by the dormant varicella-zoster, also known as chickenpox, becoming active again, often [physio-pedia.com]

  […] pathologic studies have demonstrated damage to the sensory nerves, the sensory dorsal root ganglia and the dorsal horns of the spinal cord in patients with this condition. 9 Clinical Presentation Herpes zoster typically presents with a prodrome consisting of hyperesthesia [web.archive.org]

Physical examination of the skin rashes and its characteristics forms the basis of the diagnosis. In addition, history of pain and the appearance of rash on one side of the body confirm herpes zoster. In many instances, tissue scrapings can be cultured for the virus, but such a kind of method is time consuming and delays diagnosis and consequent initiation of treatment.

Laboratory tests are of no importance in diagnosing herpes zoster. Also, no type of imaging studies is indicated in diagnosis of the condition. However, MRI can be carried out in cases when there is development of encephalopathy and myelopathy.

Herpes zoster cannot be cured; the symptoms can however be managed with antiviral drugs. These medications also reduce the risk of developing complications. Antiviral drugs such as famciclovir, valacyclovir and acyclovir are prescribed for effective management of the rash and blisters [8].

Along with antiviral drugs, numbing agents such as lidociane are also given in form of cream or gel to be applied on the affected area. In order to control the associated symptoms of herpes zoster, steroid injections can also be administered to shorten the duration of the episode [9].

The prognosis of the disease condition is extremely favorable with the rash that resolves within 10 to 15 days. Children and otherwise healthy individuals have a better prognosis as compared to the elderly population [5]. However, if treatment is not initiated in right time, it can cause debilitating and life threatening complications in the immunocompromised population [6].

The virus known as varicella zoster virus (VZV) causes herpes zoster. The VZV virus belongs to the Herpesviridae family. The exact etiology that causes the reactivation of the virus years after initial exposure is not yet known. However, individuals with poor immunity status are known to fall easy prey to this disease. Certain disease conditions such as HIV and cancer can predispose the individual to develop herpes zoster [2].

It has been estimated that in the US, about 99.5% adult aged 40 years and above are susceptible to reactivation of VZV. An individual of any age group who has suffered varicella early in life is susceptible to develop herpes zoster as they age. It happens probably because of lowered immunity. It has also been reported that, individuals who have suffered an attack of herpes zoster are at an increased risk of developing another attack of the disease later in the life. About 4% individuals are susceptible to develop recurrent attacks of herpes zoster [3].

The causative organism varicella zoster virus causes two discrete disease conditions, varicella and herpes zoster. Herpes zoster majorly occurs in those individuals who have suffered varicella early in their life. It is not a contagious disease, but individuals can pass on the virus to healthy individuals. As a result, the healthy individual would develop varicella and not herpes zoster.

After an episode of varicella, the virus remains in dormant state in the dorsal root ganglion. An attack of herpes zoster occurs, when the virus gets activated for reasons not clearly understood. However, certain factors such as decreased immunity or stress are known to predispose an individual to develop herpes zoster [4].

Herpes zoster can be prevented through vaccines namely varicella vaccine and varicella–zoster vaccine. The varicella vaccine used for prevention against chicken pox is now commonly used for children. This vaccine is also recommended for adults also who have never had chicken pox.

The FDA has approved the use of varicella–zoster vaccine for individuals aged 50 years and above. This vaccine significantly decreases the likelihood that individuals would develop herpes zoster. However, this vaccine is not indicated for individuals with weakened immune system [10].

An episode of herpes zoster is short lived and manifests as skin rashes in children and adults. Individuals who have suffered from varicella (chicken pox) can develop herpes zoster later in life. Once varicella is treated, the virus stays in dormant state inside the body and is not eliminated. Years after the initial exposure, the virus often causes episodes of herpes zoster [1].

Definition

Herpes zoster is a viral infection characterized by development of skin rashes with blisters specifically on one side of the body. The rash is confined to a small portion and appears as a single strap of blisters.

Cause

The virus known as varicella zoster virus causes herpes zoster. Individuals who had suffered from chicken pox early in their life are more prone to develop herpes zoster. The virus stays in dormant state in the body and gets activated when it gets favorable environment to grow. Individuals with poor immunity profile are at an increased risk of developing herpes zoster.

Symptoms

Individuals with herpes zoster develop painful rash along with blisters on one side of the body. In addition, certain percentage of affected population may also experience fever along with general weakness.

Diagnosis

No laboratory studies or imaging tests are useful in diagnosis of herpes zoster. Careful physical examination of the skin rashes and its characteristics helps in establishing a definite diagnosis of the condition.

Treatment

Antiviral agents along with corticosteroids are administered for treatment of herpes zoster. For providing relief from the uncomfortable symptoms of the rashes, numbing agents such as lidocaine are also given to be applied on the affected area.
