Pollen count has been very high where I live (UK) yesterday and today and will be for the next few days. I have the most awful hay fever with red, itchy eyes, extremely itchy nose, throat and ears and nose is also runny / a bit blocked. Any antihistamine that I've taken previously has made me nauseous, with headache and drowsy so I'm reluctant to take them. I suffer a little from health anxiety so I'm also worried that I might react badly as my throat is already itchy... could it swell up and cause breathing difficulties? Does anyone know what is the best one to take with the least amount of side effects as they all say that they can cause anaphylactic shock... Or is there a natural alternative that I could try?
