Mine took about a week of pain... then the pain went away for 2 days ... then KAPOW! Rash + Pain overnight... then worse, and worse and worse for about a week then slowly better over 2 weeks.
They told me that if I would have caught it BEFORE the rash and started anti-viral that it would have greatly reduced the time I spent as a ball of pain and pregnant-woman-killing machine ... so you may be in for a lighter ride.
