Hello, I m 56 year old, I weigh 138 and I do have high blood pressure. My BP has been under control with my medication that I take every morning. I m not a smoker nor do I drink, I m careful about my diet and wieght. However, once every few months I start feeling a discomfort in my chest, my head fuzzy, light headed and some dizziness, sometimes my eyes get blurry. When this is happening I feel pretty bad and just want to be laying down. Can you tell me what can be causing this?
