Help my daughter over the last 6 months has had passing out episodes mostly at night with a few during the day she is out for about four seconds but takes up to three minutes to come to I have had ECG , EEG blood tests eyes checked the only thing left to do is a blood mapping which I don't want her to have , these episodes she has there is no muscle spasims or jerking no taste or smell before but some times she gets a headache +heavy body feeling ?
