The bone pain from the colony booster generally doesn't last more than a few days and tends to be confined to the larger bones. It absolutely sucks, but it is due to a specific process and shouldn't continue past that. General pain from chemo is something else altogether and can, as some of us have found out, go on for far too long.
I've tinkered around with a variety of analgesics and even wandered into the world of Gabapentinoids to try to get some relief. I can totally understand your not wanting to take endone Indefinitely. Can you get access to a pain specialist?
