Cause

The cause is the chickenpox virus (VZV), also known as human herpesvirus 3 (HHV-3). The first infection usually appears as chickenpox in childhood. Although immunity develops, the virus remains dormant in the nervous system and can be reactivated later. People with a fully functioning immune system are not at increased risk.

Symptoms

Pain often appears first in the area of the affected nerve, and the rash follows two to three days later. In 50–56% of cases the intercostal nerves (chest area) are affected, and less often the back, arms or legs.

In ophthalmic shingles the face and eyes are affected; rarely, partial or complete loss of vision can result from scarring of the cornea. If the facial nerves are affected, temporary paralysis or loss of taste may occur.

Treatment

Early diagnosis and prompt administration of the right pain-relief and antiviral treatment improve the symptoms and speed up healing. If you suspect shingles, contact us without delay.
