So, you know those white little bumps on your tongue? You can get them and they stay for about a week. They drive you nuts and you scrape them against your teeth and they get worse. They come alone or in groups...
What causes them? They drive me nuts and I haven't been free of them for months! (I am healthy too so don't knock me down there!)
I do know that about 50% of people get them...and they can be referred to as lie bumps.
