I have been sniffing / runny nose but ONLY the left nostril

This answer was rated:

hi. i have been sniffing / runny nose but ONLY the left nostril since November 2019.not every day, but often, morning, afternoon and evening.i do have a digestive issue, if linked? but i read it could be spinal or brain fluid leak ....Could be an unknown allergy, but why is only 1 nostril affected?

Hello -

It could be that you have a sinus issue on the left side only.

While a spinal fluid leak is a possibility, that would be more clear, water like fluid from the nose that would be fairly continuous.

Perhaps it would be best to get an ENT doctor to evaluate you here.

this fluid is not running out of my nostril, but i have to keep sniffing

OK, that doesn't sound like a cerebrospinal fluid leak then.

It sounds more like a sinus issue on the left side.
