When we keep our finger tips over our blood pipes (arteries) which are located close to skin then the throbbing sensations can be felt. There is an artery
called 'superficial temporal artery' which passed up the temple region and that is what you are feeling. You can feel it i almost all people (Try it !!). It is not a common feature of aneurysm
. however you can always consult a physician to clarify your doubts.
