I've had hiccups/weird noise sounds for years?

It began years ago when I was about 13/14 and I am now 18, I make a hiccup sort of noise and it's very loud and uncontrolable, I do about 4/5 a day but I used to do loads and it used to be louder!! It is very loud still and very embarrassing!!! I throw my head back when I do it and comes back at random times I can't atop it! What is wrong with me...? Is it torrets/tics or something it's a sort of loud random noise!!!
