Hello. For a time now, i ve felt like something is moving in the back of my troath. I cant sleep because of this. I went to go see 2 doctors, and they used a tiny flashlight to see in my troath, but they didnt see anything. Im scared that it could be worms! feels like something is moving uo and down, and if something is going to come further up. What is the possibility for that it could be worms? :( could it be something else?
