Hello, I have a friend whose lips suddenly go blue and her face pale, she becomes unconscious for about 5 to 10 seconds, last time she even urinated without being aware of it. The next day she is usually all right. She tells me that this is happening approximately once a month , it has happened about 5 times.She is 70 plus and has lots of problems. Her blood pressure is usually 120-70 and her pulse 75 bpm. She has something wrong with the vertebrae of her neck and also a heart condition that was controlled some months ago. Could you tell me what this could be and to which specialist to take her? Should we take her to an emergency service? Thanks a lot.
