I have had these type of symptoms--and had had them disappear the next day. It never occurred to me that it was an allergic reaction. Yes though, I have had other terrible obvious allergy symptoms since 50. I have a tickle in my ears and and an itchy nose year round. I also keep windows open all winter here in DC. It's just too stuffy and hot in the hot otherwise. No real colds and no flu--so far. (I had a flu shot, of course, but still.)

Allergies. We live in Florida right now the pollen in unreal. My car was yellow yesterday. It's supposed to rain tonight. Hoping that will wash some of it away.

Sounds like I feel when I have an allergy "attack".
You can develop allergies at any time in life.

... but feel perfectly fine this morning! It was bad last night - throbbing head, stuffed up sinuses, runny nose and sneezing. Could I be developing allergies this late in life? I have never been allergic to anything before. Or when you get older does your immune system kick into high gear faster?

I am new to this Over 50 stuff.

I also live in Los Angeles where we are having unseasonably warm weather and I always keep the windows open.
