My throat feels tight, what to do? Help!?

Hi people. I'm 17 years old. So just a day after Xmas and my throat started to get tight. This is 3rd day now and my throat is still tight. It is harder to breather then usual, though not as hard that I would die. When I wake up in the morning I feel great for 1-3 hours and then it starts again to be tight. It is very annoying and I don't know what to do. I don't want to go doctors just because I sit there for 10 hours and all they give is parecetamol. But in either way, can any of you let me know what does this mean that throat is tight ? It's like a rope on my neck. Please only good answers and thanks alot for helping me out.
