So sorry Steve that you're not well. Hope you get better very soon.
My husband always suffers badly from hay-fever every year, but just now he's started sneezing and snuffling rather early. I'm wondering if the unusually warm, sunny weather has brought some tree pollen or other pollen into the air. There are lots of hazel catkins out around here, and maybe it's that. Piriton/Piritese at the ready!
(It's not Covid, as he has to test himself twice a week, being a school cleaner, and the tests are always negative.)
