Introduction
In general, uncontrollable clear nasal discharge accompanied by a sore throat may be caused by cold exposure, dry environment, common cold, allergic rhinitis, or acute nasopharyngitis. Appropriate measures such as general care or medication can be chosen based on the specific situation to alleviate symptoms. Daily precautions include staying warm and adjusting clothing according to weather changes, maintaining indoor air circulation, and regular cleaning to reduce allergens.
Under normal circumstances, uncontrollable runny nose with clear fluid accompanied by sore throat may be caused by cold exposure, dry environment, common cold, allergic rhinitis, or acute nasopharyngitis. General care measures or medical treatments can be selected based on specific situations to improve symptoms. Detailed analysis is as follows:
1. Cold Exposure
When cold pathogens invade the respiratory tract, nasal mucosal blood vessels first constrict and then reflexively dilate, leading to increased secretions and clear watery nasal discharge. The pharyngeal mucosa becomes irritated and causes pain. It's important to dress warmly in time, apply a warm towel to the nose, drink more warm ginger tea to dispel cold, and avoid further chilling.
2. Dry Environment
Prolonged exposure to dry environments leads to moisture loss from the nasal and pharyngeal mucosa, damaging their protective barrier and making them prone to irritation, resulting in clear nasal discharge and sore throat. Use a humidifier indoors to maintain proper humidity, drink sufficient warm water daily, and avoid spending long periods in air-conditioned rooms.
3. Common Cold
Viral infection triggers upper respiratory inflammation, causing nasal mucosal congestion, swelling, and increased secretions. When inflammation spreads to the throat, it results in pain. Under medical guidance, medications such as compound paracetamol amantadine tablets, isatis root granules, or ambroxol hydrochloride oral solution may be taken, along with ensuring adequate rest.
4. Allergic Rhinitis
After exposure to allergens like pollen or dust mites, an allergic reaction occurs in the nasal mucosa, producing excessive clear watery secretions. Nasal congestion forces mouth breathing, which irritates the throat and causes pain. Follow medical advice to take loratadine tablets, mometasone furoate nasal spray, or montelukast sodium tablets, and avoid known allergens.
5. Acute Nasopharyngitis
Pathogen infection of the nasopharynx causes acute inflammation, increasing nasal secretions while inflammatory stimuli affect the pharyngeal mucosa, causing pain. As directed by a physician, take cefaclor capsules, Pudilan anti-inflammatory oral liquid, and use physiological seawater nasal spray. Gargle with warm saline after meals.
In daily life, pay attention to staying warm and adjust clothing according to weather changes; keep indoor air circulating and regularly clean living spaces to reduce allergens. Maintain a light and easily digestible diet, avoiding spicy and irritating foods. If symptoms persist for more than one week or worsen, seek medical attention promptly for accurate diagnosis and treatment.
