I developed allergies to cats (and about 348 other things) about 5 years ago. I have had cats all my life...and now I have 3 furry, bathing obsessed, dander producers
and, with the exception of a bad flare up here and there, live just fine.
I had to have surgery to remove polyps that grew due to untreated allergy attacks. Then I started the shots twice a week...but still had to have a second surgery. My specialist told me shots will work for about 1/3 of the people who get them.
I just had a bad allergy attack a couple weeks ago and have been looking into a lot of things..
Best thing to do is take something like Singulair (rx...really good but pricey), Zyrtec or Claritin daily (I use the Costco brand) to prevent allergies and get an electrostatic filter for your a/c and clean/change it once a month. Some have told me recently to put a u/v bulb in the coils of my a/c (found out one is already there...I just have to replace the bulb so I can post later if I really feel a difference or not) and vacuum vacuum vacuum! I recently got a canister and it is really easy to vacuum the furniture now (I actually tried the whole "not gonna let the cats on the bed" thing for about 8 hours
....Maddie wasn't having any of that nonsense
All that said...I hope your reaction was just the corn and you won't have to deal with any of this again because allergies are THE PITS!!
Oh, one OTC allergy medication that I took this last time that worked really well is Chlor Trimeton!! This is not for daily use...only once you already are having a reaction.
