I have a severe allergy to grass pollen, so I know what an allergy feels like (I know it's not a cold in other words!).
Last night, I spent the night outdoors at a friend's house, and I got a nettle rash type thing on my legs from sitting on the grass. Although it itched like crazy, it went down pretty quickly.
I also got a runny nose, and couldn't stop sneezing. I took a fexofenadine when I got home, and this seemed to sort it, but it's back this morning, and my eyes have also started streaming. What could I be allergic to (I don't normally have any allergies at this time of year!). . .?
