Hello, I started getting headaches about a year ago and i had never got them before, one ended me up in the e.r. and they did a c.t and it came back fine, now i get throbbing sensation on one side of my head and it only last about 10 min maybe more then i get a headache all over, my doc thinks it is migrains but i don't have any other symptoms like sensitivity to light e.t.c. should i get another test done? i'm worried. i worry to much perhaps.
