the discharge is normal colour i would say, white to grey, slightly yellow some times.
When i sleep, usually on my back, my nose doesnt run, but when i wake up in the morning, i feel blocked up and will need to blow my nose a few times just to clear the airways. Then after ive showered and am getting ready for the day, my nose will start running again through out the day. - i always have tissues on me.
i did cut the bridge of my nose about 15 years ago, and have a small scar, but that the only injury i can think of.
i would say i am generally allergic to dust, when i am cleaning my room, alot of dust comes up and i will start sneezing and my nose will run. Other than that, no allergies.
hope you can help.
