What might be causing my headaches?

• For about half a year, I've been having moderate headaches that feel like my brain is swelling up and building pressure in the back left and right sides of my head, right behind my ears. Sometimes, this pain is even present in both my forehead and behind my eyes. At the same time, I become very light headed and strongly crave sugary foods. This headache usually becomes stronger if I am exposed to very bright lights. When these headaches happen, I usually have something sugary, along with a tylenol, and lie down, sometimes taking a short nap, until I feel better again. Recently, I've been getting these headaches and accompanying symptoms at least once a week and they're beginning to scare me. I don't have medical insurance so I can't just walk into a doctor's office and expect to be diagnosed for free. **In case this helps, I am a female, 20 years old, I don't smoke nor drink, and I'm not taking any medications. Diabetes does run in my family, and my mom is hypoglycemic. I also happen to have allergic rhinitis (also known as hay fever) that I think might be turning into sinusitis.
