I really sympathise. Hay fever can make you feel miserable.
I had never suffered with hay fever until my early 40s and then suddenly I was cutting the grass one day and my eyes started itching and then went really red, swollen and jellified. I've had hay fever every year ever since to varying degrees, but I'd never made a hormonal connection. Funnily enough, last year I thought it was improving a bit, but then last week it started and it's worse than ever! Although I sneeze and get an itchy nose it's my eyes that are most affected. They've been constantly streaming, itchy and swollen all week, despite using allergy eye drops four times a day.
