Personally, I have only missed days of work for chemo treatments. My job is part office work, but also physically intense as a facility manager of a large campus. I get a ton of walking and lifting in each day. But by the end of the day and very tired. I have learned that you have to listen to your body and not exceed what it is telling you, for if you do, you will take several days to recoup. At times, I get brain fog, which does hinder doing paperwork, but my job is flexible enough, that I can get some physical items accomplished and come back to it later.
The peripheral neuropathy has only been a nuisance to getting things done for me.
