I'd try the poxclin I recommended on your original post. S seemed to scab over much more quickly than C who I didn't use it with. She does still have some scabs 3 weeks later though. Calamine only temporarily sooths, and doesn't help to prevent scaring. You'll just have to ride it out I'm afraid. My eldest had it mild and had fully scabbed over after about a week. The problem is new spots can appear days after the 1st, so when the 1st have scabbed over you can have more appearing. I know how frustrating it is as I had to keep C off nursery and you really wouldn't have known she had it. In fact, it was only when S got it that it confirmed it was the pox that C had.
