I have had a severe burning sensation on my tongue, tongue ulcers, a swollen tongue, periods of slurred speach, a sore throat, canker sores and dry chapped lips since October. I have seen two doctors, had a tongue biopsy, tried magic mouth wash, lidocaine mouthwash and carafate mouthrinse. I discovered today that other people online are complaining of similar symptoms and like me they have been using sensodyne toothpaste. In addition to discontinuing use of the sensodyne, what can I do to alleviate some of the pain - I have been in agony for two months.
