I Felt Suddenly So Hot That I Began Pulling At

I felt suddenly so hot that I began pulling at my clothes in a meeting. Someone said I was very flushed. I stood up and walked a few steps, felt very dizzy and nauseated and sat down on the floor. I forgot the name of the woman who spoke to me but remembered it within five minutes. I am a 69-year old woman in excellent health with normal BMI, low-normal blood pressure, a good cholesterol score. I don't smoke and drink 10-14 glasses of wine per week. Breast cancer survivor.
