Does anyon know if

Hayfever can effect your breathing?

 

Yes, you will cough up blood every time you try to speak.

 

your head will explode in a gooey fashion.

 

It does something similar to drowning.

 

Yes it can affect your breathing, it can also make your eyes water and stuff. Google it, google won't tease you as much as some of the members here are doing :b

 

Yeah, it can, but it's rarely happened to me just usually makes my eyes itch like mad and water with mass sneezing.

Also, protip: Don't lie down when your in a room of plants and you haven't taken your hayfever pills.
