Tamoxifen, Bone aches, brain fog and poor memory. Any one else experiencing these?

in Day to day
Hi all,
I tried to put this in the tests and treaments category but for some reason it won't let me.
So I'm on week nine of taking Tamoxifen and having some serious concerns. Apart from the ever popular hot flushes, my back and hips are aching constantly. Not too bad through the day when I'm moving around a lot, but quite painful at night in bed or sitting.
This one is the more worriesome to me at the moment.
Very poor short term memory I have to write notes and set alarms for everything at the moment. I am struggling at work when it gets busy. Poor concentration. I am going from the middle of one task to another instead of finishing the first. If it's super busy i.e paperwork, phone ringing, people asking questions, making appointments all happening at once it's like my brain shuts down into this cloud of fog and I have to walk away for 10 minutes so I can think again. I have trouble remembering words during conversation. Occasional light headed, dizziness. Just generally feeling like a bit of a space cadet at the moment.
So much so, that I asked my GP to schedule a brain scan!
So I decided to stop taking the Tamoxifen for a few days and guess what? Within 48 hours I was clear headed.
This isn't constant some days my brain works fine LOL,
Just wondering if anyone else is experiencing any thing like this.

I started on fish oil to help with aches and pains which made a huge difference (to joints and brain) as well as getting back to my weights and stretching exercise. Always discuss concerns with your oncologist. We all worry when we have aches in our bobes and joints. I ended up having a back CT for terrible stiffness and pain ...which I had to a lesser extent pre chemo. Well all fine apart from arthritis, spurs and bulging discs. My exercise routine has helped this so much I hardly have pain there now. (Or maybe it's overshadowed by my excruciating quad and bicep pain from my workouts instead. Haha)
I had light headedness for a while after chemo which turned out to be cardiac related and the medication I was on. It's okay now. I needed to ensure I was always well hydrated.
Hi @kezmusc,
Sorry to hear that you have been experiencing bone aches, brain fog and poor memory, that must be very frustrating for you. Speak with your medical oncology team regarding the symptoms you have been experiencing and that you stopped taking the tamoxifen for a couple of days and felt better. Your oncology team may be able to make some treatment recommendations. Hope you are feeling better.
Had a quick google and it seems they are starting to do some research in this area.

Hubby in contrast (has his own room) gets up at the slightest noise. Turns on the TV, makes himself a warm drink, snacks on stuff then says he has trouble sleeping.
