Allergies. You can say you don't have them, but chances are it's them.
I have allergies, but not the kind you get from going outside and smelling pollen. I get them randomly. Sometimes when it rains or I take a shower. Sometimes when I wake up. Sometimes when there is no pollen outside, sometimes when there is pollen outside. It's hard to pinpoint what it is, but what I do know is cigarette smoke makes my allergies go insane since I quit.
Maybe it's that whole "your sense of smell and taste come back" thing people say. Idk...
Since my entire journey of vaping I've associated everything with my vaping.
My ears hurt? is it from vaping? my lungs hurt? is it from vaping? I have a flu? is it from vaping?
the only advice i can give is to give it a few weeks and it will be gone.
