I have been experiecing a slight burning/tingling sensation on my tongue on and off for approximately 5 years. However, sometimes its the whole tongue and sometime the feeling is just on one side of the tongue; I am feeling it on my left side of the tongue as I am writing this message. I also experiencing shading of skin from the inside of my mouth now and then. On swallowing my throat feel slightly taut. The burning/tingling sensation can last all day and sometime goes on for few days at a stretch. I love to know if anyone out there are experiencing the same symptoms or have answer to my mistery symptoms.
