I have some white thing on my tongue. it's been same size for many months now. noticed this last year. same size. hurts if I touch or rub with fingers. always erected straight and skin just attached to the tongue. it's white in color like white color round at the bottom of that blister and on top of it is pinkish white color. what to do for this? is this something serious? I have chronic jaw and tooth pain for 3 years for which I had several dental work. no relief though. then noticed this tongue blister. don't know how it's formed. Any thoughts on this please. what to do for this? it's so tiny and hurts very sore if I touch. I tried to prick it out but I couldn't.
