Hello, my tongue got a sore on the side almost 4 months ago. These have now turned into cracks. They are extremely painful. Sometimes i wake up with it stinging and hurting. Spicey foods, temperatures too hot or too cold, toothpaste and mouthwash all make it burn even more, but the pain is becoming fairly constant. I have also been having neuralgia or numbing around my ear, especially behind it. This is also increasing, and spreading. I have been having a lot of headaches as well Any idea what ails me Doc.?
