I don't think it was caused from the Docetaxel,but it probably didn't help.I have an appointment with the exercise physiologist on Friday,to change my exercise program.The oncologist said to me that walking ,even though it is great for general health,it does not help osteoporosis.There are other things that are far better,so hopefully I will find out exactly what they are.I sometimes have had the comment like" gosh you have such a lovely straight back!" Now I will be thinking,if only they knew what is really under there.The thing now is,there is not much chance I will change to an Aromatase inhibitor,because of the side effects it can have.I will probably stay on Tamoxifen,because being post menopausal,it gives you at least some protection when it comes to bones.Its all too confusing isn't it?
