I have a runny and blocked nose which I think is probably to do with hayfever. What do you suggest?

I am sorry to hear about these issues. When pollen gets into the nasal passages it can cause these symptoms as the body tries to get rid of the irritating agents. You could try our Pollinosan Nasal Spray to help soothe the area and clear it of allergens. I would also suggest limiting your dairy intake as this can make congestion and a runny nose worse. It's also a good idea to drink plenty of water and drink herbal teas like nettle which is a natural antihistamine.
