As Paul mentioned, Glutamine works wonders as does Magic Mouthwash. I added the Glutamine to the baking soda and salt rinse.
I had a couple of different Magic Mouthwash formulas. One was a swish and spit and the the other was swish and swallow. Both had lidocane in it and really helped with mouth pain.
You've done incredibly well thus far. Just keep being pro-active with symptom control.
