Hi Mark,
I had 6 infusions of Docetaxel from August to December last year (2024), and I found that my pain went away completely a week after the first infusion. In my case, the pain was caused by a met on my spine which was interfering with the sciatic nerve.
However, I was also given a steroid (prednisolone) to take daily throughout the course of chemo, which will have contributed to the pain reduction.
Hope that helps, please do feel free to ask any other questions you may have and I'll do my best to answer them.
Cheers, Craig
