Thread: light headed

Since yesterday about noon, I've felt light headed. But not dizzy. No problems with vision or feeling like things are moving. Just really light headed. Comes and goes. I have been having problems eating enough food lastely, I'll start eating it and then it just tastes bad or makes me feel like I'll throw it up, so I stop eating. So I thought maybe it was food. I ate lunch, 1 1/2 taco from taco bell (i know, real healthy). So once I got off work I grabbed a chicken snack wrap while I drove to my parents house to pick up their dog. Still didnt go away. When I got home I drank a full glass of milk and layed down. It would go away and come back so on. Today, in the a.m. wasnt feeling it much. Ate a small blueberry muffin and peanut butter and crackers, so far. It's actually more now then earlier. I sometimes have high blood pressure, but from what I read, low blood pressure causes light headed ness? Ive tried searching all over, but what throws me off is I am NOT feeling dizzy or vertigo. Any thoughts?!?!
