Hi @Stork, Welcome to the forum!!! People are funny buggers, and it does hurt when they turn their backs. As for Tamoxifen and fluid retention I've certainly gained weight and have just rejoined weight watchers yesterday to try and lose this. As for joint pain yes got that and have found my knees are the worst, I put a bolster cushion under them of a night when they're really bad and it makes a huge difference. My feet haven't swollen with fluid I just get pain in my left foot in the ball of the foot and have tried changing my work boots, runners, any other shoes that I wear and so far haven't hit on the magic formula to stop that particular ache. See if others here have any suggestions and/or ring the Bcna nurses 1800 500 258, cancer council 131120, speak to your breast care nurse, oncologist as someone should be able to advise. Big hug xx Cath
