Arimidex and Zoladex

Dear All

I do not post that often however could someone kindly give me some advice regarding Arimidex and Zoladex.

I have been on Arimidex and Zoladex for nearly two years and i was wondering if it is still effective as my body seems to be trying to prepare for having a period. Like when i had periods my breast have started to feel sore, i am suffering from spots and i have what feels like ovulation pains.
As my cancer was ER positive i am concerned that with the premenstrual symptoms i am experiencing is there oestrogen raging around my body again.

Has anyone else experienced this before and been told that Arimidex and Zoladex are still working for them.

kind regards
