Hoping to have surgery on my left nostril which doesn't drain properly. At the slightest cold I get painful infection etc but just get on with it. I've had a CT scan and am just waiting to see a specialist hopefully with view to surgery .In recent months though my nostri's been more blocked than not,and I'm experiencing symptoms which I recognise from when I had PND ie zero tolerance, low mood, irritable, lack of concentration etc. as though part of my brain just isn't fuctioning! The fact that my blocked nose causes me broken sleep and crazy dreams doesn't help. Just wondered if anyone has any knowledge/experience of this?
