The causes of frequent swelling of the bridge of the nose include chronic sinusitis with nasal polyps, recurrent polychondritis, and high intraocular pressure. 1. Chronic sinusitis with nasal polyps: in sieve sinusitis with nasal polyps, when the sieve sinus septic inflammation occurs, if the nasal drainage is not smooth, it will lead to head discomfort and nasal bridge distension. 2. Recurrent polychondritis: the etiology of this disease is not known, most scholars believe that this disease belongs to an autoimmune disease. If the cartilage of the nose is involved, the dorsum of the nose, the wing of the nose or (and) the tip of the nose is red, swollen and painful, and after many episodes of “saddle nose”, the cartilage of the outer nose is destroyed, and the outer nose is obviously deformed, and the inflammation can no longer occur. 3. High intraocular pressure: When the intraocular pressure is too high, it can compress the bridge of the nose, resulting in a feeling of swelling of the bridge of the nose, which can be seen in the acute closed-angle glaucoma symptoms. If you often have this symptom, it is recommended to actively seek medical treatment, systematic examination and clear diagnosis.
