I see this was April. Are you feeling better now? I stopped Tamox in June a few months before the 10 years mark. I had hormonal breast cancer stage 2 10 years ago with chemo and radio followed by 10 years of Tamoxifen. I was fine, actually feeling better during the first 2 months after stopping it but now I have very stiff joints and numbness in my hands and arms at night and hot flashes. I hope it will improve in time and wonder how long withdrawal symptoms last.
