Hi Sandy,
I can relate to the hot flushes and leg aches very well. I started Tamoxifen on the 12th and have had leg aches ever since. They seem to be more muscular than bone but I can't be 100% sure. Hot flushes combined with the Perth heat makes for a lovely combination - NOT! Most of my nights have been broken and I find I'm awake very early so I tend to get up - sometimes as early as 5.30!
Sorry I can't help with the bone question but I can only hope that it's muscular rather than bone. My pain is only when I move. I don't seem to get it lying in bed. Not sure if this helps. I finished chemo on the 6th so I'm not sure whether this is related to the chemo either. I start radiotherapy on Tues and see my onocologist on Fri when I start my 3 weekly herceptin so I'll ask him about the leg aches.
Good luck with your scan results and keep us informed. You will be fine and it is ok to feel scared and apprehensive. It's all part of the BC journey.
Take care. Will be thinking of you,
Alison
