Ahh the Docetaxel Devil (as i called it) I too had FEC-D 3 rounds of each 21 days apart......I'm still having side effects from it 6 months on.....my big toenails just fell of last week!.....talk to your breast care nurse or chemo nurses, they will advise on best course of management....alot of rest worked for me, and I mean ALOT! walking around the house also eased the aches.....panadol regularly and sometime a stronger pain killer was in order....things usually settled after about day 10 for me....then it was almost time to be hit again! Wishing you all the best with the rest of your treatment
