I had the chicken pox. I'll have to check with my mom about exactly what age (but old enough to remember it quite clearly...I think, based on where we were living at the time, it was probably about 6th grade--a little on the late side). Once I really had them, they were pretty much the same as anyone else's (I have lamellar too). But, I got off to an interesting start...
I just happened to have an appointment with my opthalmologist, and he and his team sent me and my mom into a panic. They thought I had something really rare, strange, and serious going on with my eyes that they were having a hard time even classifying for sure. Well, my mom and I figured it out a few days later when the pox started appearing on more tradition places on my body--but the very first ones appeared on the inside of my eyelids!
That's probably a coincidence, and didn't have anything to do with my ichthyosis...but who knows. Other than a strange start, my chicken pox were pretty typical in terms of duration, severity, size, number, etc. and my family treated it just like you would anyone else and it seemed to work.
I'll double check with my mom, and see if she has anything else to add.
