Recently, I've noticed that at the very back of my tongue, there are raised red bumps there but I'm not sure what they are as they haven't been there before. I've checked lots of websites and they say it is tastebuds but they have never been there before unless they are tastebuds which are swollen but what could be causing this. They are not sore but I can sometimes feel them at the back of my throat. Thanks for any answers!
