Hi I Have A Area On My Neck I Guess

Hi I have a area on my neck I guess right where my thyroid is that is swollen and feels like there's a huge thing that's stuck and won't go down the feeling gets worse when I try to eat as then I feel it all the way in my chest I also have developed a sore throat and I can't quench my thirst no matter how hard I try. I was told to see a Dr especially since my father had larynx cancer and I should get it checked out even if it could be nothing
