Hi Suki
I'm on Letrozole and Goserelin injections as I wad pre menopausal when I was diagnosed. I initially felt very stiff and had muscle aches, not severe, but definitely very noticeable, particularly if I was sitting down for ling periods of time, and I felt very creaky until I got moving.
I noticed that over time it settled down a lot and 18 months in its now pretty mild and stretching and keeping active with walking and aqua aerobics really helps.
I feel like the worse symptoms were caused by the rapid loss of oestrogen and now my body has adapted to living without it.
I'm waiting for a hysterectomy and ovary removal so I won't need the Goserelin, and I wonder if that will make any difference.
