Yesterday I got extremely dizzy after I ate 5 french fries, nothing else. This was followed by a dull headache in the back of my head that lasted for an hour and got better after I drank some water. I have noticed that sometimes if I eat a small bite not followed by a drink, it feels like the food gets stuck in my chest and the I get dizzy. In the past, I have been told that my blood pressure might be a little high and maybe the blood sugar as well. Any thoughts will be appreciated.
