I presume you have all the usual symptoms such as running nose, sneezing, itchy eyes and throat. I suggest using one of the allergen barriers, a vaseline type substance smeared on each nostril to try and prevent the pollen, the allergen, from causing the allergic response-all the symptoms you have described.
One of the disturbing things about a runny nose is that, if not treated, it can lead to an increased risk of asthma. The modern one a day antihistamines have far less chance of causing drowsiness so that should certainly be tried. There are also several types of nasal spray now on the market so it’s important to ask which one is best for you. I particularly like the saline washes available that can be used as frequently as you like. When you use a nasal spray try and direct the droplets into the side of the nose rather than straight- back that will give you much better relief.
Eye drops are very useful in combating irritation. I usually recommend sodium cromoglycate which needs to be used four times a day. If you own a pet remember that their fur will be full of pollen as well as your own clothes.after being outside. Have a change of clothes ready as soon as you enter your house.For lots more advice and to tailor your treatment call into the pharmacy.
