More herceptin feeling worse???

Hi I have had 12/18 herceptin infusions and am not sure whether my flu like symptoms are down to this or Femera!!! I seem to be more tired and feel weaker after each infusion. Has anyone else experienced this? 

Hi rosie I had my 11th herceptin yesterday and after each time I have felt like I have flu I must admit the symptoms have got slightly worse my problem is the achy joints but like you I can’t differentiate if it is that or the letrozole I seem to be worse in a morning or if I’ve been sat for a long period love judi

Hi ladies. I’ve had 8/18 Herceptin infusions so far and the main thing I’ve noticed is the stiffness and pain in my knees. I am like an old crock when I get up in the morning, and also if I’ve been sitting down for a while. I’m not on any hormone therapy, so it’s definitely the Herceptin causing it. I can fall asleep at the drop of a hat too, but I’m having radiotherapy at the moment so it’s probably that. Have a lovely weekend everyone xx
