What Are These Bumps In My Throat?

For the last year I have been getting bumps in my throat. They come and go, I don’t have them every day. Sometimes I’ll go weeks at a time without having one. I typically only get one bump at a time. They are flesh colored and oval shaped. They aren’t painful. They are usually lower in the back of my throat kind of hidden behind the tongue. All of this started after I had strep throat 3 times in 5 months. I haven’t had strep since the bumps started. What is this?
