I have been getting them with each treatment. They last for a week and start to get better and then come right back with next treatment. The baking soda and salt water soothes a little but not a lot. They have a numbing rinse but sounds like you are using that already. I haven’t tried it yet. I have a bad gagging reflex. I lose about 10lbs my first week following treatment and gain some back the second week after I can eat more regularly. Do you also get thrush? I get that too in my mouth so I brush constantly and keep off spicy foods.
