I've always suffered from hay fever as I'm allergic to grass pollen. This meant that I usually had to take antihistamines from about April til July each year, and this controlled it.
However, since last summer the sneezing hasn't stopped! I wake up with a blocked nose and before long it starts to run and I'm constantly blowing my nose. So I have to take an antihistamine every day, even now, in the middle of winter. I seem to have developed an allergy to so many more things than just grass - even the waft of perfume from someone on the bus can set me off into endless fits of sneezing.
Has anyone else experience this?
