This may be herpes zoster viral infection. It is also known as shingles. It is characterized by a painful skin rash with blisters involving a localized area. It is caused by varicella zoster virus. Predisposing factors are old age, immune-compromised patients such as HIV infection, patients on chronic steroid and chemotherapy. Shingles resolves within 3–5 weeks, but secondary bacterial infection and chronic pain due to post – herpetic neuralgia may occur. Duration of recovery from post – herpetic neuralgia is uncertain and variable. Advice 1. Apply locally aciclovir 3% ointment five time daily 2. Ibuprofen 600 mg thrice daily per oral after meal for 5 days for pain relief 3. Ranitidine 150 mg twice daily for 5 days to prevent acidity caused by stress and ibuprofen 4.
