I don't know if they'll go along with any deviation from protocol, including the "tools" they use. But I'll tell ya, something has to be done about my burned lips. Today I woke up with a blister on my lower lip on the opposite side from where the radiation is supposed to be targeted the most. I have to keep my lips constantly sticky with my arsenal of moisturizers, the most effective of which is the Bag Balm but it feels like I'm wearing an extra pair of lips.
I also developed what I think might be thrush, but of course being the weekend won't get to have anyone look in my mouth until Monday. So the recommendation over the phone was to use the mixture of salt/baking soda mouthwash until then. OMG! The salt was TORTURE on my poor burned lips (outside and inside). I'm now using just baking soda, and it seems to help. What were they THINKING?!
