About a year and a half ago i had this little white spot in the back left side of my throat. It was sore everytime i swollowed. My dentist said it could be that i cut my throat when eating something. Eventually it went away but it took quite a while. Well today i noticed the same white spot in the exact same place as it was a year and a half ago. With the same symptoms. Im worried because its weird how its exactly in the same spot and looks the exact same. Does anyone have any idea what this could be? I was also wondering if warm salt water would help?
