Yep definitely sound like flushes to me too. My face usually wouldn't get flushed or sweaty, but everything else would. I would suddenly get this overwhelming heat coming from within that would mainly affect my torso area. It wasn't like experiencing an outside heat, like on a hot day. It felt totally different, and it was pretty unmistakable. My heart and breathing rate would increase, and I would get this sense of anxiety, that would last for maybe 5 minutes or so. Then at night it would often be replaced with feeling cold.
Fortunately HRT fixed all that, but I can still experience night sweats occasionally - not all the time, but I might still get one maybe once a week or so.
