I (16) just woke up one morning in January last year ('07) and discovered my nose had swelled up and was red outside as well as inside ( one nostril was red raw inside). Since then I have been allergic to almost everything in the enviroment - I can't walk by grass or trees without my nose swelling up (and releasing a watery discharge) and this happens all year round!
My doctor diagnosed me with rhinitis but antihistamines he prescribed me don't work, or on the occassions that they do, not for very long! There are no other symptoms apart from the sinuses.
Could he have misdiagnosed me, I mean does everyone develop allergies literally overnight? It has ruined my life!!! I used to be active and involved in a lot of sports but can't pass a field now without my nose swelling up and it is so uncomfortable and irritating.
