When people have a headache, they put their fingers or knuckles on 2 spots on their temples each. Then, they move the 2 spots around with their fingers / knuckles around without lifting the fingers / knuckles off or moving the fingers / knuckles away from those spots.
Is it natural to say "circle your temples with your fingers/knuckles" or "rub your temples with your fingers/knuckles"?
I don't think we say "rub", because when you rub something with your finger, the finger will not be fixed on just one spot but on many spots around it.
But, for this action, the finger stays in contact with the fixed spot all the time.
