I would guess it's not cancer! But, of course it is always safe to be safe than sorry. Talk to different doctors until you feel someone takes it seriously and that there's a solution to your problem. You might want to have your thyroid checked if you haven't already. I have the exact same problem, however. My throat feels all throbby and achy like I've been holding in a cry for a really long time, and it's usually accompanying (following or prior to throat tightness)difficulty breathing and chest tightness. And we're not the only ones. There are lots of other people experiencing the same thing, which is some comfort! I haven't found a solution for it, but keep blowing it off so haven't even talked to my doctor about it to be honest. I am also young. I've heard that it's caused by anxiety and that some doctors won't take it seriously. I saw your post and saw that you posted in May and that no one's responded to your question. So maybe you don't need an answer anymore but I thought just in case, I'd write what I know. Here is some of the information I've found. Good luck!
