Our expert says:
If possible try to get antiviral treatment like acyclovir- you get generics that is not that expensive but you need to take it within 48 hours of the blisters starting. Then keep the area clean and use a antiseptic cream like Betadine on the area to prevent secondary infection. This may become very painful and you may need strong paintablets like Dolorol Forte. If the blisters dry and the area is still very painful, you can try Sloans liniment on the area.
