Tired after Paclitaxel Chemo completed. ( EC prior)

Thanks kmakm, I had thought of doing some rehab. My  thighs and knees are both very weak, since all of the Chemo.
I had some arthritis before, but it seems much worse now.
I haven't done enough walking and/or exercise during Chemo. 
I hope to improve this with a little walking, as my tiredness is slowly improving.
I have it on my to do list, to seek out a rehab programme. I feel like a much older woman, for the moment.
Like you, I've just started Radiotherapy and will start Letrozole soon after.
