When it is at its worst, my tongue is covered in painful sores and I have cracks all over my tongue. The magic mouthwash I have of malox, benadryl and lidocaine is the only thing I have found that works. The lidocaine numbs my mouth and tongue and after a few days of using it, the sores usually get better. It's hard to know if you have Sjogrens.
