I've been taking tamoxifen for about 3 years now, following breast cancer (surgery but no chemotherapy). I'd been suffering quite badly with peri-menopause symptoms prior to all this - heavy periods, pelvic pain, fuzzy head, anxiety/mild depression, mood swings, constant thrush etc.
Since taking the tamoxifen I've noticed I don't get the mood swings, or (generally) any pelvic pain. And my anxiety is less. That's the good news!
But my 'fuzzy head' ran into one long hang-over type feeling for about the first year or so of tamoxifen. Thankfully, that has slowly improved too

.
My periods got lighter and lighter and stopped after about 6 months. Since then I've had two episodes of spotting and two hysteroscopies, the last one earlier this year. The endometrium is thickened, and a couple of small polyps were found, but thankfully nothing sinister. It's a worry because tamoxifen can lead to endometrial cancer (oh joy!).
I just wondered what other women taking tamoxifen might have experienced in the way of meno symptoms? It's only the past few months that I've noticed my night sweats getting worse, to the point where I can barely get comfortable (blanket on/blanket off, all windows open and so on). It's even happening in the daytime now. I assume they're hot flushes - it feels like an intense warmth and a general 'clammy' feeling. Much worse in the warm weather.
And I have various joint pains, mostly shoulders/hands/feet, which I suspect are actually the tendons rather than the actual joints. I was treated for tennis elbow about a year ago (very painful!) and had physio. Thankfully it healed after about 6 months, but the other aches and pains are similar though less intense.
Oh, and my sleep is often broken these days

I'm hoping to swap to arimidex on my next yearly check up, which will be March 2017. Hopefully there'll be no more bleeding before then (fingers crossed!).
Is anyone else on tamoxifen/arimidex or similar?
