Has anyone suffered thrush in their mouth from chemo?

i am really struggling to get rid of it and need advice.

ive had it every time I've had chemo but each time it's gradually got worse and after my final chemo 3 weeks ago I still have it. Even after using all my meds and mouth washes. It just won't go!

i also have a terrible cough, which I've always got alongside the thrush as it irritates my throat but my cough is just really annoying me now I want it gone.

has anyone experienced this? And did it eventually go or did you have any natural remedies that worked?

please help
