I think that's pretty common @Jrcn Many of us struggle with a variety of new aches and pains post chemo which seem to feed off each other. Sore feet lead to sore knees lead to sore hips.
Following my second chemo experience in a decade, I was at the point of despair; I seriously thought I would be crippled for life and never move properly again. Just over two years later, most of my issues have either resolved or become manageable. I had no trouble at all after my first chemo experience in 2006 so I guess that shows how variable experiences can be. Keep moving if you can, that definitely seems to help. Mxx
