Shingles medication free#
Young adults and children are most likely to be free of pain. A few have severe pain without any eruption, called zoster sine herpete. Most, but not all, adults have acute, neuritic pain in this phase.

The eruptive phase occurs when the skin lesions appear.Shingles diagnosis is difficult before the characteristic rash appears.In the pre-eruptive phase the skin may be tender but there are no lesions to see.The patient may feel unwell with malaise, myalgia, headache and fever but these symptoms may abate as the eruption appears.This usually lasts for a day or two but it can be over a week before the characteristic eruption appears.In the pre-eruptive phase there is no skin lesion to see but 80% of patients complain of burning, itching or paraesthesia in one dermatome.
Shingles can be divided into the pre-eruptive phase, acute eruptive phase and chronic phase - postherpetic neuralgia (PHN). HIV, Hodgkin's lymphoma and bone marrow transplants all present a high risk.Consider underlying immunodeficiency if anyone presents with shingles affecting more than one dermatome. Incidence and risk are increased in the immunocompromised patient.Increasing age significantly increases the incidence, morbidity and mortality of shingles.The lifetime risk is estimated at one in four.Ĭhickenpox can rarely be acquired from a patient with active shingles, as the lesions shed virus (transmission is by direct contact or droplet spread) but shingles is not caught from contact with a person with chickenpox. The annual incidence of shingles for those aged 70 to 79 years is estimated to be around 790 to 880 cases per 100,000 people in England and Wales. The incidence and severity of shingles increases with age. Shingles is seen as a disease of older people but it can affect all ages, including children. All these people are therefore at risk of developing shingles. At least 90% of adults raised in the UK are immune, having been exposed in childhood. Shingles may also affect cervical, lumbar and sacral nerve roots.Ĭhickenpox is a very common childhood illness. If the mucocutaneous division of the VII cranial nerve is involved, the lesions in the ear, facial paralysis and associated hearing and vestibular symptoms are known as Ramsay Hunt syndrome. In immunocompetent patients, the most frequent site of reactivation is the thoracic nerves followed by the ophthalmic division of the trigeminal nerve (ophthalmic shingles), which can progress to involve all structures of the eye. Reactivation of the virus is thought to be associated with immunosuppression as a result of a decline in cell-mediated immunity. There is not always a clear reason for a flare-up but associations include ageing (most patients are over 50 years old), immunosuppressive illness, or psychological or physical trauma. When this happens, the virus travels down the affected nerve over a period of 3 to 4 days, causing perineural and intraneural inflammation along the way. It may lie dormant for many years or many decades, kept in check by the immune system before flaring up in a single dermatome segment.
After this the virus lies dormant in the sensory nervous system in the geniculate, trigeminal or dorsal root ganglia. Primary shingles infection usually occurs in childhood, producing chickenpox (varicella) although it can be subclinical. Shingles is caused by the human herpesvirus-3 (HHV-3).
