I begun post menapause 8 months ago. Symptoms began 4 yrs ago very infrequent and a yr ago its many times a day. An episode starts with intense nausea quickly changing to a passing out feeling quickly changing again to the warm flooding sensation over the entire body then followed by all over heat that's so intense far from a hot flash. After switching meds with Dr B., still an opiate the symptoms aren't as sharp and have blended some.
Also, at night, laying down wide awake I get a sensation that I'm not getting enough oxygen and almost panic for a moment. It goes away quickly. Seeing an autonomic neurologist in Aug at Stanford hoping for answers.
