I'm 68 woman and for the most part in excellant health. No prescription meds & no over the counter meds. Eat a very healthy diet. I never have headaches and this past week have had a headache that is persistant. No fever or cold or flu related symptoms. Today I am experiencing some dizziness, almost like I might faint. It is not from hunger as I had eaten breakfast & lunch. The dizziness came about 1 hour apart. Any thoughts?
