I have a condition called... Perennial Rhinitis. It's sort of like hayfever all year, so I take medication for it.
Before 1990, I never had a problem either, but one too many broken nose from a fight, and they decided it's best to fix my nose, and straighten it. Before this first operation, I never had sneezes!
Then 12 yes later, and around 8 operations on my nose for various bits, I'm left with a nose, that... Isn't allergic to anything, but I'm also allergic to everything! For a few years, I would have multiple sneezes several times a day. I would have steroid I j xtion, which worked wonders, then the people in charge of prescriptions I wasn't allowed them anymore.
