I'm a 20 year old male and I've been having this symptom since early May. I'll attempt to give some information that might help anyone rule out certain things. Thanks so much! My appointment to have this looked at isnt for another month...
It all seemed to coincide with what seemed to be a strong but quick (under a week long) nose cold, and since then my nose has stopped running but for these past two months my nose has been clear but I've had an amazing amount of mucus draining down my throat. I've been spitting it out constantly.
I haven't been coughing it up (I don't know if that's because I spit it out before it gets too far down) and I don't have difficulty breathing, though sometimes when I swallow solid food there seems to be some pressure on the way down. I don't really choke on it, but it is disconcerting when compared with the symptoms of esophageal cancer.
My throat also feels dry no matter how much I drink. I do not have any known allergies and I have never had a sinus problem before.
It is possible that I have GERD (it's not painful, but I do get an acidic sensation every so often.
I have been a heavy gum-chewer up until a couple weeks ago, when my teeth were adversely affected by how much gum I went through.
I also have mild tremors in my hands, toes and a few muscle groups. Might muscle issues in my neck cause something like this?
If there's anything more specific anyone would like to know, just ask.
I'd really love to stop worrying about this one.
