Hi and welcome to ECF in 2021,
Without knowing anything about the e-liquid, the coil, the tank, the device or the power used;
I would think what you are describing is related to seasonal allergies or perhaps a sinus infection.
Just to be sure, go see your doctor if 24 hours vape free doesn't resolve the discomfort.
If a vape free day changes anything, then it's time to review your kit and liquids.
Cheers
I
