Everyone is different, I had a recurrence on Tamoxifen and since treatment finished have been on Arimidex and now Aromasin. I had zero side effects on Tamoxifen and quite a bit on the others, but I feel its due to chemo too. Its a tough question, nobody has to take them, for me though? I'd sooner know for a few side effects I gave myself the best chance of not risking another recurrence. Hugs xoxo
PS Im still in pain alot I admit, though I take magnesium in water daily with Vit D. I also take Panadol osteo and I find thats enough to settle things.
