A few things that helped me with the chemotherapy bone pain:

Daily soaks in a bathtub with Epsom salts using lukewarm - not hot - water.

Hot showers before bed using a shower chair (loaned for free from local senior center). Target the water on the joints that hurt the most.

I followed the showers by applying CBD cremes/lotions or a product called Traumeel to my joints. I could get a few hours of good sleep by doing that.
