at least once a month, there is a white spot comes up in my mouth, sometimes on the tongue, sometimes on the wall of the mouth, sometimes on the throat . It really hurts when I eat or drink hot or spicy stuff. It comes and goes after a week and then a few weeks later it comes back on another place in my mouth (I brush my teeth twice daily with an electric brush and also gargle twice daily before brush with Listering or Scope). I know this is very popular among Asians like me and I was told because my internal body has extra heat (explain the Chinese way) that it has to come out somewhere to release the compressed enery(???) . I don't know if this is true but it is very anoying (hurt when eating).I went to my family doctor and he said I just garle with Scope (I do everyday) and take some ...pain killer like Mortrin or Tylenol. I want a real cure and not a temporary relief. Please help...I am still in pain
