I Am Having Symptoms That Concern Me. I Am 62,

I am having symptoms that concern me. I am 62, diabetic with good numbers. I take a cholesterol and blood pressure meds. I have new symptoms that confuse me. Persistent headaches, light headedness, forgetfulness. These are not usual for me. The headaches are preceeded by jagged lines of color in my field of vision before the headaches start.
