I've been lucky not to have any allergies but I do get mild asthma and started getting a little bit of hay fever a few years ago, I think set off by tree pollen. I usually take an over-the-counter antihistamine until it stops but this year its gone on and on! I had a polyester throw in the living room and I've noticed my hay fever symptoms are much better now I've removed it. Could the two things be connected?
