I walked all through chemo, although I think I was very lucky during chemo as I had very few side affects. Not sure if the exercise had anything to do with how good I felt during chemo or not. My treatment was through winter so I wore a hoody mostly to hide my bald head but it also kept it warm.
During chemo my sister had to rehome one of their dogs, she asked me to take the dog for a week...I still have her a year later. I love her so much and she helped me go walking every day of treatment and was great company. I feel grateful that she came into my life at that point.
Take care.
