I know it's annoying but your body is obviously doing it for a reaosn. So best endure it and think that it is doing it for the best! An antihistamine will only suppress symptoms that need to come out. You probably have a cold or hay fever. Try to blow your nose rather than wiping it, as that's what makes it sore.I find that going outside for a walk in the fresh air can help dry it up too.x
Thanks for your answers. The bunged up bit has now turned in to a rather painful chesty cough. I went to bed with snuffle babe and a bottle of sudafed last night. Dont you just love summner colds!
