Hi there. For about three months now, I have been experiencing a blocked nose. It s not just any blocked nose, it s just one side of the nostril, and it keeps producing green mucus and in the mornings I wake up congested and my nostril oozes out mucus over my pillow during the night. It isn t a cold, but sometimes I get rather headachey behind the nostril and one side of the head. Sometimes it clears up. Than the next day it s all congested in that one side of the nostril again. It s really effecting my sleep and I m quick sick of blowing my nose all the time. Especially after three months or so. Thanks for your time. Ben, New Zealand.
