I use cheap saline nose drops to seriously reduce pollen allergies causing clogged sinuses. Clogged sinuses get infected by cold virus causing post nasal drip in throat. That results in lung infection and cough. Nasal drops are less than $3 at Walmart.
Thanks for the suggestion, but I can’t do that. Can’t use a Neti Pot, either - it feels like I’m being waterboarded - though many people swear by them.
As I said, so far nothing serious, just general eye itches when the Ragweed is in bloom.
