Last week I had to visit a doctor in France, for an ear infection caused by a cold and blocked sinus, and they talked about washing my nose out as if it was a normal thing. Anyhow, I thought it was worth a go, even though I wasn't sure how to do it. I mixed up saline in a pint glass (roughly teaspoon salt:pint, which I think is normal saline proportion) using lukewarm water, and snorted and blew out my nose until clear, nostril at a time if needed. To my surprise, without going into description of the emissions, it really seems to help and ends up feeling good. The mild discomfort of sucking down some saline is easily outweighed by the benefit.
Anyone else wash their nose out? Care to share techniques? I would deffo recommend to anyone with a cold and blocked nose.
