This is a really bad year for it, and 'they're' saying that next year is going to be bad too, sorry.
I'm not too bad a bit snuffly, but OH used to really suffer.
This is whats worked for him, might help others or not. .
Antihistamine at night, as well as the morning, the pollen is dropping then and cause he's warm we have the window open. . .
So for him the symptoms would build up and he used to wake feeling grotty. So taking an antihistamine then was like throwing a welly up Oxford street.
This helped a lot
Vaseline around the nostrils and in, before he leaves the house.
Eye drops and sunglasses the whole time while outside.
Paracetamol when bad, helps as a antipyretic and the aches and dried up his nose a bit.
And the biggie, we found some local honey and he started taking at least a spoonful of that a day. That will be no use now and may make you worse, but after your symptoms go, give it a few weeks for your histamine levels to drop and start.
Theory is it desensitises you, I thought it was woo till I looked it to it, and for him it's gone from him hating leaving the house between April to June/July to being a bit of a bother. . .
It's really crap isn't it.
Oh and one other thing is we have patio doors that are open all day if/when the weather is good. We have voile full length curtains on them if its a good day we wet and wring out the curtains and rehang, sounds like a faff but it means we have air moving throughout the house (we both coworker from home a few days a week) it's a cheap form of air conditioning and a damp curtain catches the pollen rather than it moving in to the house.
Only issue is I have to take the curtain down 'cause its full of pollen. . .
