I guess I have been vaping for 2.5 years now. I do have a bit of sensitivity to VG and some flavours. Its usually ok if i vape no more than 20% VG, but some flavours seem to add to the irritation as well. Not exactly sure which ones as i only vape tobacco juices but i think juices like FSUSA wyatt earp and Juicewhore Ultimate pipe have some flavour in with the tobacco that doesn't help in particular.
I suffered from sinus issues, infections and the headaches that come along with it since I broke my nose a few times playing football in my teens.
I often go through 3 month phases where i only vape when drinking or sometimes less than 1ml a day when not vaping. During those times i really notice that i usually have no sinus issues at all. When I am vaping alot I would guess at least once a month I have sinus issues.
I always keep saying to myself I should vape 100% pg, no flavour nic juice for a month to see if this helps, but never do it. Should really give it a go, but miss my flavours too much and like the extra vapour a bit of Vg in the juice gives. When I was smoking my sinus issues were alot worse than when i am vaping though.
Anyone else have sinus issues and can notice its worse when vaping some types of juices or vg/pg %'s etc ?
