thank you, because i went to the doctor for the same thing. I thought it was a thrust and he told me" oh its because your house is dry." but now that i remember, it happened to me before and my old doctor said it was a yet infection on the tonuge andgave me a prescription which cleared it in like two or three days this doc was bugging so thank you very much im going back to that doc with my new found kwonlegde
thrush can feel like it burns. it should easily scrape off and its a yeast infection. Hairy tongue looks like how the name is. The papilla on your tongue grow long and look like grass. If you do not brush your tongue you will get a white coating that eventually turns black and leads to what is called, black hairy tongue. Which just means it turned black.
I would see a doctor to confirm thrush or not b/c you will need a prescription to get rid of it, if it is.
