Shingles is mainly referred to as herpes zoster and usually takes about 3-4 weeks to get better gradually. Herpes zoster is a skin disease caused after the body has been infected with the varicella-zoster virus. It is mainly characterized by unilateral distribution of the body with clustered blisters along the peripheral nerves, accompanied by burning, numbness, pain, itching and other sensory abnormalities. It usually takes about 3-4 weeks to heal with standard antiviral treatment. About 10 days after the use of antiviral drugs, the viral activity is basically suppressed, but the symptoms of nerve damage by the virus will persist, and many people need to continue using nerve-nourishing drugs for a longer period of time in order to achieve the therapeutic effect. Herpes is contagious and can be spread by contact. Close contact with people around you should be avoided during treatment.
