New to the forum. Thanks everyone for the posts about joint pain - at least I now realise I’m not imagining feeling like a really old woman at 56. I’ve had bc three times. First time 7 years ago it was non invasive so had surgery and radiotherapy. Second time a year later was invasive so I had surgery, radiotherapy and was put on tamoxifen. Side effects were minimal and tolerable. Last year brought the third diagnosis resulting in a mastectomy and being changed to letrozole. Finding the joint stiffness the worst, although I also notice an effect on anxiety and mood. I’m also on zoladex injections which might be exacerbating things. However phoned bc nurse today and she’s suggested I stop letrozole for a few weeks and if it makes a difference they’ll try me on a different drug. Thanks to posts I now have the names of alternatives, like exemestane, that I can ask about. Maybe I’m just feeling a bit sorry for myself as my tissue reconstruction was cancelled in April due to lockdown so still waiting! Need to try to stay positive! Take care.
