Hi Tracey
I had a weird throat and voice while I was having chemo too. After each treatment my throat would get really sore, like it had been stripped of its lining, and then my voice would go croaky. I never completely lost my voice but it certainly wasn't the same for quite some time. Even now (I finished my chemo on 29/12) I find that I sometimes feel like I am straining my voice to talk more loudly. I have quite a quiet voice anyway and when my voice is playing up it can be quite annoying!
Hopefully once you have finished your chemo it will come back properly. How many more treatments do you have?
