LOL ...
Same happens to me but in particular season of fall in February when the winter ends and summer start.
I always feel sneezing and in fact, start sneezing before lunchtime when body clock throw alert and gallbladder start releasing acid in the lever which starts producing gases. When the gas increased and start moving upward for burping, I feel like it creates little pressure irritation in nose and trigger sneezing. It is really crazy and uncomfortable feeling as eyes start tearing and runny nose for at least a minute. After burping, everything looks normal like nothing happened.
The same cycle continues after lunch or dinner till food is digested and stop creating gases.
Many people say that this is due to pollen in the atmosphere or body's internal system preparing for coming days of summer.
What medical science says about this? any doctor, please comment.
