Welcome to HCM.
I understand your concern regarding your infection. Herpes zoster
can be very painful and annoying. I want to make you understand that herpes causes inflamed nerves along the area of infection which causes this itching and irritation.
This episode will take at least 4 weeks to completely heal. Please continue your medications regularly. Try to focus on other things other than your symptoms. Keep yourself busy to divert yourself from the pain and itching.
I hope I have answered your query satisfactorily.
