I feel so badly for you and I do hope you get some relief soon.
I am starting my 1st riund of it in 2 weeks... have to say I am really crapping myself. Oncologist did pain a 'lovely' picture of bacterial infections, trush, nerve pain and such. I kind of glossed over it and ignored as mich as I could as I already suffer from horrid mucle pains and neuralgias, get both trush, UTIs and various infections at the drop of a hat and figured it could not be much worse.
I guess it can... and it sounds like it will :(
Wishing you all the best and hope you do not have too many rounds left to go through.
