I am a 44 year old woman. I border HBP and I am currently on meds. I walked the treadmill earlier, at dinner, took my BP pills as I always do after I eat. Within maybe 5mins I experienced some light headedness and I have been off ever since...probably going on a little over 2 hours. I get up and feel as if I could fall over....like I moved too fast .....I had some red hot blotchiness on my chest earlier, no itching just red. It has since gone away. Was thinking my blood sugar was too low but it s been 3 hours and a a glass of OJ & a glass of Milk and still feeling off....NOT as bad but it s still there .....what could it be ?
