I am a 61 yr old diabetic female who has a defibrillator due to getting vtacs. I m very active, rarely ill. Today I was light-headed several times. I assumed that I am slightly dehydrated because I don t drink fluids like I should. I forced myself to drink a few bottles of water today. Just now I again, was light-headed, then all of a sudden it felt like I got an IV of hot liquid. I felt it go through my body, down to my feet and up to my face, with my ears and face flushing. Blood pressure s good and sugar is good. I still feel this heat across my shoulders face. I don t want to go to the ER if it s nothing because it will cost me $200 that I don t have, but I don t want to shrug it off either.
