Long term herceptin only anyone ? Need some advice from experience please

Hi ladies, yes I too have had the crazy itch, mostly on forearms & front of hands but went up to shoulders & under arms. My naturopath gave me a homeopathic blend of drops which seemed to help although you have to take them 8 times a day & then every 15mins 1 hr b4 bed which can be hard to manage! It contained sulphur & urtica 
unfortunately I have had further Mets recently diagnosed & operated on so I’m changing from herceptin & perjeta to kadcyla so the itching has stopped which is good but more Mets not so
