Feels like there's something in my throat

Please help,

I am 14 years old and for the past few months it feels like something is stuck in my throat and my throat keeps making these growling sounds. I saw that some people who described it had G.E.R.D, but i dont have heartburn (I've never had heartburn in my life) My parents say it's just allergies, but I've had this feeling for awhile and it keeps going on even if I haven't eaten anything recently or if my allergies are fine. It feels better while I'm drinking water, but it doesn't feel any better when I stop drinking. Please help, this has been going on for awhile and it feels like something is stuck! it feels like I'm choking on food and I can't swallow it. It's mostly in the back of the bottom of my throat and it feels a little better for a few seconds if I burp (sorry that's gross)
