I agree with Boger. It's your call. Taking your snake to the vet isn't a dumb thing to do. The dimples look weird and even experienced keepers can't tell you why she has them. Maybe the vet can. On the other hand, your snake is behaving normally and those same experienced keepers aren't alarmed by the dimples, so it also wouldn't be dumb to wait and see what happens. You should do what you feel most comfortable with. The funny thing is that you may not be able to get an appointment right away, so you may have no choice but to wait and see.
