Something in throat?

Rachel • “If you can dream it, you can do it”

Whenever I swallow cold water or liquids it feels there’s something in my throat on the left side or in the back when I swallow and it’s never when I drink warm stuff. I gave my bf oral a week ago but we’ve been tested and we don’t have any STI’s. It feels like there’s hair in the back of my throat or something and I don’t know what to do
