I did four rounds of AC/Chl then did four rounds of Docetaxel. The Docetaxel was the hardest to endure and I had the aches and pains you speak of. My last treatment was 17 months ago and I am still getting better.
I spent lots of my time during the Docetaxel treatment in a warm spa bath. It was the only way I could find relief from the pain. I had endone and other pills but the warm water seemed to help me the most.
Best of luck getting through it. I hope you are using cold caps to try and protect your hair.
