Hi Larns81
ask your mums doctor for a script for FUNGILIN lozenges. I was given these when I had a very sore mouth from the chemo. There is also a mouthwash that I was given by the chemo nurses, but unfortunately I cant remember what it was called. Ask the nurses where your mum has her chemo - they will know what it is, but get the lozenges as well!
I'm not sure about the rash, but I know before my hair started falling out, I had a very sore scalp and it was very tingly. Again, check with the chemo nurses - I found that they know everything.
Good luck.
Di 🙂
