Nasal mucosa swelling, also known as nasal mucosa enlargement, is most commonly seen in rhinitis. It is an enlargement of the nasal mucosa caused by the irritation of the nasal mucosa due to inflammation in the nasal cavity. In terms of pathological changes in the nasal mucosa, there are chronic simple rhinitis, chronic hypertrophic rhinitis, caseous rhinitis, atrophic rhinitis, etc. In terms of the urgency of onset and duration of the disease, it can be divided into acute rhinitis and chronic rhinitis. The cause of the disease is not simply the conventional lung, spleen and kidney Yang deficiency, stimulated by wind and cold, pollen, dust, mites, odor, etc.; its onset is not mainly in the cold winter season, but in the three seasons of spring, summer and autumn. It can be seen that the etiology of the symptom is intricate and complex, and it is based on the dysfunction of the internal organs, or the deficiency of qi and blood, imbalance of yin and yang, and the failure of clear qi to rise, or poor microcirculation, resulting in the loss of nourishment of the nasal mucosa and the formation of nasal mucosa inferior turbinate variation. The differentiation of the nasal mucosa variation from the different color and different morphological changes is conducive to identification, and the real cause of nasal mucosa swelling can be analyzed more effectively. The changes in the swollen nasal mucosa were summarized into 3 types. These 3 types are all of this deficiency and the combination of internal and external etiological pathogenesis, and wind evil is one of the main causes of induction. 1, nasal mucous membrane swelling dark red or purple: most patients of this type due to genetic factors or kidney qi deficiency, can not warm, or depression, liver and gallbladder stagnation, resulting in the invasion of evil toxins, lung qi depletion, residual evil stagnation, qi stagnation, blood flow obstruction, autonomic balance imbalance, parasympathetic excitation increased, and neuropathic rhinitis. 2, nasal mucous membrane swelling pale and pale white: most patients of this type due to congenital deficiency, or acquired loss of nourishment, the stomach is not fragrant, the spleen is not healthy, lack of qi and blood, low autoimmune function, lung spleen weakness is unable to perfume water and fluid, water dampness up the nasal orifice and clear snot, snot clear and not sticky, stimulated by wind, dust, mites, odor nasal, pharyngeal, eye mucosa and the entire upper respiratory tract mucosa, so that nasal itching and eye, pharynx, ear canal. Sneezing and runny nose is even worse in the morning. 3, nasal mucosa swelling light red and pink: this type of patients due to the deficiency of both yin and Yang (mainly lung and kidney yin deficiency), lack of qi and blood, clear gas does not rise, the nasal mucosa can not be normal qi and blood to fill the nourishment, stimulated by wind allergens. The nasal mucosa gradually becomes enlarged, light red or pink in color, and the sense of smell is dull. It may be accompanied by fatigue, lack of food, bloating, dry throat, itchy throat, dizziness and tinnitus, or red cheek and irritable heat, heat in the hands and feet, light red tongue with little coating and thin pulse.
