People say that the elevator doesn't go all the way to the top or that someone's elevator doesn't go all the way to the top to mean that someone is stupid or mentally ill. I get the feeling his elevator doesn't go all the way to the top.
Too much mucus buildup in throat is most often due to excessive post nasal drip. This can be caused by allergies, flu, and the common cold. The phlegm that accompanies an infection can hang around long-term. It usually clears up within 4 to 6 weeks, but for some people the problem can drag on for months.
Post-nasal drip occurs when thick or excessive amounts of mucus drip into the back of the throat. The inflammatory substances in the drip coupled with trying to clear the excessive mucus, causes irritation and discomfort. Excess mucus running down the throat may cause hoarseness and lead to a cough. In fact, post-nasal drip is the most common cause of coughs. Other common symptoms include tickling in the throat, snorting, constant clearing of the throat, and difficulty breathing. A sore throat results due to the continual attempts to clear the excess mucus.
