By the way, someone has previously mentioned using a TENS machine to manage chemo bone and joint pain.
I have not had a chance to do so with Chemo but I suffer from chronic pain due to broken plus missaligned spone and cannot use painkillers due to liver damage so I own a very basic TENS machine that has saved my bacon on manu ocassions. It basically not just helps me by reducing pain but makes it possible to walk where pain otherwise stops me as while applied to the hip or leg or back area inflammed at the time I can walk and get about with minimal pain.
The place I got it from is out of stock but I found the same machine in a different online shop in case you were interested in finding a cheap one. It is very basic and on eBay you might be able to get it $10-15 cheaper but I figured legit business is always a safer bet.
This machine is small and runs on AA batteries so very portable making it easy to place it in a large pocket or handbag while still attached to you thus peoviding pain relief even when walking and wanting to leave the house.
