Tamoxifen and headaches?

Does anyone suffer with headaches on Tamoxifen? My daughter has just started having really bad headaches and it always seems worse in evening after taking tamoxifen. She is left with a dull headache all the time but with really bad headaches every few days. She has been taking tamoxifen since beginning of january. Naturally she is getting really worried so i thought I would ask if anyone else is suffering headaches.

I’ve been getting this too. I’ve been on Tam for 6 weeks and Zoladex for 3. I have a constant daily headache and nausea. I think it’s quite a common side effect but it’s very hard not to imagine the worst
