Good morning. I, like you, did not have any side effects from Tamoxifen until 1 1/2 years into taking it. I had incredible knee pain and swelling last year, some muscle aches, weight gain, and I can totally relate about the hair - what a mess!
I’m 48 and now almost at 3 years of taking Tamoxifen. My dr would like 5 so I’m going to try to make that. I try to stay active as I do think that helps.
