I'm 53. Went through the menopause around 45 ish. Had an awful few years of symptoms but have been much more settled for the last 4 ish years. No obvious symptoms and feeling fine. No hrt. Recently though, I've been feeling horrendous. Constantly hot and flushing, racing heart, palpitations, exhausted, terrible sleep, even more hair loss. GP is at a loss. Nothing obvious. Heart OK, bloods fine, thyroid OK. Is it possible therefore for menopause symptoms to flare up again? Many of my symptoms are very menopause-y.
