jacquelina,
I just read about your mouth and face pain, it sounds awful. I probably shouldn't be posting this until I can remember just exactly what it is I'm trying to tell you, but I do recall reading about compounding pharmacies that are able to make mouth lozenges called "troches" that are specifically for the mouth pain you are experiencing. I'm sorry I can't remember the exact name, it has been a while and unfortunately I don't retain info all that well

If I come across it I will definitely let you know. sorry you are suffering, jenny
