For over a year my tongue has been cracked, the pain is aweful when I eat. If I eat anything rough, like potato chips or even hard candy, the pain is almost unbearable. It feels like Iam eating glass, my cheeks and gums feel like they're torn to shreds. I use a mouthwash containing peroxide which I can hardly stand to keep it in my mouth the pain is so bad. I've shown this to my Dr. and my dentist, but cant get anyone to give me a diagnosis or maybe a biopsy. I have other symptoms like feeling like an electric current is running through my body. I feel like Iam vibrating and jerking. Does anyone else have these symptoms. It is a terrible thing to go through.
