I googled side effects of Tamoxifen today as been having terrible stiffness/aches all over, queasiness, kind of like bad flu symptoms. I've only been on Tamoxifen for 2 weeks after having surgery on 16 May to remove a lump and 2 lymph nodes (which were clear). I'm amazed reading that so many people are complaining of the same symptoms. Shoulders and neck pain like Sarfan, feeling tearful like Chriss. Mood swings. Just generally feeling awful. I'm seeing my oncologist on Tuesday so have noted down questions to ask her as I'll probably forget when I get in there!
I was prescribed Tamoxifen rather than Letrozole because I take Alendronic Acid once a week for osteoporosis. I must say though that the osteoporosis is manageable and I've been able to get on with things, going long walks etc. After a 45 minute walk in the park the other day I was stuffed!
I'm glad I found this forum by accident!
