i know what you mean! i had to take a break bc i couldn't finish the whole pack (it was the seven day ones) and i started back up again two days ago and a whole new sort of pain has begun. when the strips are on i will get a random extremely sharp pain in different locations each time but it feels like i need to rip the strips off and make it stop. but just as soon as it's come it's gone just like that. i think just keep spacing it out, and keep trooping. it'll be worth it when your teeth are pearly white!
