I had my tonsils out 18 years ago, but about 6 months ago I started having these little hard, white spots develope on the back of my throat. They eventually go away, but then come back within a week or so. I have also noticed what appears to be a tonsil growing back on the same side of my throat as the white spots (though the spots are not on the tonsil). I am a 36 year old woman and quite overweight, but otherwise in good health. Do you know what could be causing this and what I can do to treat it? I should mention that I have had a bad taste in my mouth (not horrible, but unpleasant) for about the last month. Any help would be greatly appreciated! Thank you.
