Suddenly got all the symptoms (sneezy, blocked nose, itchy eyes) over the past few days. Seems to be at home and in the office (which I was in last week.. but won't be going back to for a while)

Anyone else ? Any ideas ? Can't think of any personal environmental changes.

It can suddenly come. Some years I am allergic, some years less and it only started when I got older, never had it before.

I've been sneezing a lot this week, I wondered if it was some specific pollen event but I also definitely have a cold so it's hard to tell.

Have you turned on the heating? That always aggravates my allergies/sinus issues. The dry air and burning dust aren't a good mix.

Also, in my office, they have been aggressively cleaning it due to positive COVID-19 cases. Many people have complained that the harsh chemicals have caused issues for them.

Otherwise, perhaps you are having a reaction to a food you are consuming?

These were my only symptoms when I got tested positive for Covid a month back. I was actually quite perplexed by this weird allergy until I got the text result

Otherwise, dust mite? Mould?

I have my worst allergies in the autumn some years. The heating system does seem to trigger something, but also there's plenty going on out in nature that can trigger allergies at this time of year. Or you've caught something and those are your symptoms.

Get a new box of masks, maybe. I react to some masks for some reason.

Absolutely. I went fabric, my asthma couldn’t handle the surgical ones.

I regularly have hayfever from May - August which is easily managed with antihistamines. Last month and last week, I've had to take them again due to high pollen levels in this unusually warm autumn. Last Monday my symptoms were full on, as bad as any summer bout of hayfever. I took antihistamines for 5 days and the symptoms died down within 2 days, but allergic rhinitis can affect you all year round.

The farmers are doing their various harvests which is kicking up a lot of dust. It is amazing how a harvester, cutting sunflowers about a metre off the ground, sends so much crap into the air.

According to Meteo Swiss there is no pollen in the air at the moment but, ...

In addition to an antihistamine, and there are plenty these days which don't make you drowsy, try taking an anti-inflammatory like Ibuprofen. That should reduce swelling in your nasal passages.

Me too - surgical ones.

So strong message to the OP - get tested. With the weather we've had recently this is a quiet season for allergies, although the föhn coming from tomorrow might liven things up a little.

These kind of symptoms can even appear because of the clothes you wear. Maybe there is some kind of sweater made of material that hasn't really been worn before?
