Headaches everyday =(?

Ok, I get headaches everyday...Usually behind my eyes or my forehead and sometimes my temples. Never really on one side never really towards the back of the head. My head will throb If I bend to pick up something or move really fast...Im thinking its sinus, but my nose isnt stuffy and I have no fever, sore throat nothing. I deff feel pressure over the bridge of my nose. I CANT afford to go to the doctor as I would really need a CT-scan and have noooo insurance. My mom gets headaches alot, and my sister get headaches everyday too. Could this be hereditary??? I will have health insurance soon and thats when I plan to go to the doc but in the mean time. I alrady wear contacts, I grind my teeth pretty bad (could this cause headaches)..not so much stressed....and I have been breathing in steam latley..any other suggestions or ideas if u think this is serious??? Im 26f and never had any medical issues before. Any input is really appreciated. Thanks Ladies
