Hayfever

Can I ask a question regarding hayfever;

I've never suffered from hayfever before but have recently had a really blocked up nose/ throat and my ear is constantly ringing (hurted at first but now just annoying), my question is does this sound like hayfever symptoms or something else?

Is it an itchy/scratchy sort of hurt, or a swollen and throbbing sort. If it's the former, that's like my hayfever - I get itching from the tree pollen (starts around Valentines Day some years) then that goes away and about a week ago I started feeling dull, heavy, aching in my joints and a few days ago it had become a sore throat, perma-semi-blocked nose and a slight hissing/roaring sound in my ears. If it's the latter, it may be an infection, so get yourself to a doc. Bright yellow snot is a give-away sign of infection.
