Hot flashes can be caused by a variety of things...and just for your info, men get them, too. Best not to assume it's menopause without checking it out with the old doc first.
From personal experience, I know that some medications and some vitamins cause hot flashes or flushing. I also know that some conditions cause similar reactions...thyroid disease, lyme's disease come immediately to mind but perhaps, an advanced search of the open boards would alert you to other causes.
I think it is interesting that you experience these without sweating.
