Hi, all! It's been seven years since I had my palatectomy and maxillectomy. I have been cancer-free since then. Recently, I have been dealing with sores on the tongue, which when biopsied showed dysplasia. My tongue is incredibly painful -- enough so that I don't want to eat -- so my doctor prescribed Magic Mouthwash. It seems to last only about 1 hour, but the directions say to use every 4 hours. Can I use it more often than directed???? Help!
