@TaraV my medical oncologist recommended it for joint pain. It must be very difficult to find a corner in your day with a young child .Maybe family/ friends might help or even if viable before child is awake or after they are asleep ?
I was embarrassed into walking by a breast cancer lady in her 70s tbh. I joined a local support group and met a remarkable little country lady. Twenty years earlier on a trip around Australia she found a cancerous lump in her breast in Mackay Qld.She had promised her daughter in Adelaide to return with her husband for her 21st which birthdate was also shared by her husband. She took her husband to the airport then drove to the hospital and had a mastectomy.She stayed in hospital until Friday and then had to leave so returned to the caravan park where kind fellow travellers organised basic foodstuffs and kept an eye until her husband returned a couple of days later. She told me she walks every morning at 5 am regardless of the weather and was still cancer free 20 years later.
I took up daily walking and was winter ( not at 5 am though) wet and cold and I believe it helped a lot with joint pain as my body adjusted to Letrozole gradually over a few months.It also helped with my mental/ emotional state as frightening time first year after diagnosis.Unfortunately currently am struggling with plantar fasciitis from walking long distance in a Cairns in attractive but unsupportive footwear.If you can learn from my stupidity by choosing appropriate walking footwear that would be a blessing.I hope to be back walking ASAP.I found I like walking much to my surprise basically I listen to music and think about things as I go along.
