I started tamoxifen (my chemist dispenses Genox) and was anticipating side effects but have not had any of the headaches or nausea that were potential side effects. No hot flushes yet either. My oncologist was talking about sending me to a study (if I wanted to go) that sees if the tamoxifen is active in my body (she says it may well be but this would confirm it) as some people don't metabolise the drug. I certainly would participate in this study IF it is still going as I am not keen to take this stuff for 5 - 10 years if its not doing anything.
I do have joint pain in the knees and fluid retention still but I think it might be left over from chemo, and for the knee pain may well be the weight I gained during chemo putting pressure on. I have been back to the gym but been on a cruise so no weight loss yet! it will come.
good luck - hope the side effects lessen soon for you
