Abdo & back pain

Well I still have the swollen left leg, now to add to it abdo. & back pain which radiates down said left leg. GP thinks it is the tamoxifen. BCN has made appt. for me to see ONC as she feels my body is fighting against the Tamoxifen and they probably need to add Zoladex to quieten my ovaries.
Anybody else had these symptoms?
