So, right before the thyroid trouble started, I went to the dentist because I had gotten these 2 white spots (not your average "lie bump") on my tongue. By the time I went to the dentist two weeks later, after using that Peroxyl stuff for the entire 2 weeks, they were gone. That was the second time I had them, in the exact same spot - tip of the tongue. They were sore only when I ate or drank something. Anyway, That was in March. I am starting to see them come up again in the same spot again and the kind of burn feeling is starting again. I bought some more Peroxyl (BTW this is made by colgate and can be purchased at any drug store), but would like to know if this or similar has ever happened to anyone else. I just wonder if it is connected to thyroid or just some strange "my body" thing.
