What do you do if your are allergic to all these? are you taking meds?
I'm the same as Jleigh plus I'm allergic to more. I take Telfast regularly (180mg dose). At my worst, I was taking three a day as prescribed by my specialist. I also use a prescription only nasal spray daily, Nasonex. It's so expensive but partially covered by my private health and works really well. I also use a saline sinus rinse when I'm really bad or suffering from sinusitis, which happens several times a year.

I'm seeing an allergy specialist again soon and will possibly go through desensitisation treatment again (I had it done for grass and dust mites 12 years ago). It's a long process (around 2 years) but it certainly helped last time. They can treat up to four allergens at once now too so that's a real positive for me.
