The absence of nasal discharge but clogging as soon as you lie down is considered to be related to various nasal diseases such as colds and nasal polyps. This symptom occurs mainly due to the change of body position during the onset of the disease, which can lead to changes in the amount of congestion of blood under the nasal mucosa.
1. Cold: the onset of cold is mainly characterized by sneezing, runny nose, nasal congestion and other symptoms. The stimulation of inflammation can lead to congestion and swelling of the nasal mucosa, causing the nasal cavity to become narrow. When the human body is lying down, the blood return speed of the nasal veins will be slowed down, and the excessive blood accumulation in the nasal veins will lead to further swelling of the mucous membrane, which will trigger the symptoms of nasal congestion.
2. Nasal polyps: are a variety of factors stimulate the nasal mucosa caused by abnormal hyperplasia disease, is a class of occupational lesions. If the nasal polyps in the standing position does not block the nasal cavity, there will be no symptoms of nasal congestion, but lying down under the action of gravity, the polyps may change with the position, thus producing the feeling of nasal congestion.
When there is no nasal discharge but the blockage occurs as soon as you lie down, you can actively seek medical attention for systematic examination to clarify the diagnosis and the cause of the disease.
