Hi Welshcake, can I put my two penn'orth in. Hot flushes come in all sorts and, in peri-menopause, I would have what I called 'hot moments'. Sometimes I wouldn't even feel hot but I recall being in a meeting and everyone staring at me, looking shocked. I looked in a mirror and my face was beetroot-red ... but I felt only mildly warm. These hot moments came and went with no pattern - occasionally I would suddenly become so hot in my core, within a matter of seconds, and then half a minute later I'd be back to normal. So my advice to you is, yes it probably is a hot flush and a mini one (believe me, when you get a bit one you will know!). Laugh it off as a 'hot moment' as I did, and start changing your wardrobe as, from pretty much now on, you will be looking at cottons and linens and layers as that cardigan will be on, off, on, off as your heat goes up and down. Polyesters and artificial fabrics really make the flushes worse. Oh, and if you can, dump the brassieres as they are full of elastic and other heat-retaining fabrics ... try to go au naturel on weekends if you can.
Re. memory ... yep that's a hormonal thing. Suddenly you can't quite find the word you wanted to say, or have forgotten something on your shopping list despite reminding yourself all day. Silly stuff. So keep a pen and paper in your bag, and next to your bed, and by your chair in the lounge, and write things down. Make lists, lots of them. That's how I do it, as I think of it I write it down.
Hormones affect all of your body and mind and I hadn't realised how much. Peri-menopause can be a bit of a bumpy ride with unpredictable periods, and occasionally really heavy periods, so I always wore panty liners and always carried sanitary pads in my bag in case I was caught out.
Gosh, reading this sounds so depressing. Sorry, but I wish someone had told me all this stuff as I went into peri absolutely blind and worried myself silly about the anxiety and mood swings, thought I was going mad until I started the hot flushes and researched and found I was in peri. So good luck. Ask away.
