I am a 60 year young female, who has had the same problem I will tell you about twice.
The first time I was at work, felt good, no pain, no problems, nothing but hot sweats, over and over. I went to the ladies room, and had to slide down on the floor, because of dizziness. The EMS staff checked my pressure, it was okay, and my sugar it was okay. I just blacked out, but never stopped talking as far as I know, I was told I did. Well, feeling good again yesterday, went to the store, and when I got in my car, it felt like the car was doing a dance, and I was very weak, and dizzy. EMS came, blood sugar 85/ BP117/76, no pain, etc. Help,,, Althought I am going to the Dr on Wed
