Tracy, don't listen to Dr. Google. You'll just panic.
This year in my area PA, we had an unusual amount of rain in the spring. Consequently, we have more than the usual crop of weeds, and grass, and pollen, and mold spores. Now we're having few weeks of less than normal rain, so we're having more dust.
I've been free of allergy symptoms since starting the shots years go. That is, until this year! Suddenly I'm having all the itchy mouth, ears, throat. I saw my allergist, but all she did was prescribe ear drops. I'd already started taking loratidine OTC in the morning and Benadryl at night.
So, listen to your real doctor. We're having a bad summer.
And, PS: we're not doctors on this forum, or most every other forum either, so we don't know much and can't really diagnose or treat anyone. But, good luck!
