Hi @Aussiegirl19. So sorry to hear about your diagnosis.I too have a mum and younger sister who are thrivers and was diagnosed November last year. I also had 2 lumps. Ditto to all of the above. Peter mac in Melbourne produce their own mouthwash which is bicarb and salt based but tastes nicer! I also was prescribed the pink gel for mouth ulcers which numbs things and works a treat.Try not to overfloss as the gums are a lot more sensitive and you can upset them. Good luck with your chemo. I'm glad you have your sister and Mum there to support you in this.All the best!
