Question:

I saw someone already asked this question. My symptoms are much the same. I have no eye tearing but have a constant feeling of needing to sneeze and a constant dripping from my right nostril only. I had 2 root canals done on my two upper front teeth. Shortly after the local was injected I kept feeling the need to sneeze. Hoping this would wear off after the numbness wore off I shrugged it off. After the local wore off it got worse. It`s only the right nostril that flows and if I`m not sneezing I constantly feel the need to sneeze. I have no cold and or allergies. Could a nerve have been aggravated by the injection and/or dental work?

 

Answer:

It is possible that this could occur although it is not a recognized problem with dental local anesthesia. I say this as yours is the fourth or fifth question like this, so I presume it does occur.

One always wonders if there is some irritation of the dental nerves from dental surgery that might also have this effect, but it appears that local anesthesia may be the cause. I am at a loss to understand this problem, especially once the anesthetic has been eliminated from the area.
 
One could easily come up with theories while a patient is numb, but less likely afterwards. I am sorry I can not be of more help. It may be of value to have an ENT physician do a nasal endoscopy to rule out any other issue that may be causing this.
