What should I do if I keep sneezing and having a runny nose?

Continuous sneezing and a runny nose may be caused by environmental factors, cold air irritation, allergies, the common cold, sinusitis, and other conditions. These symptoms can be improved according to different situations. It is recommended to visit a hospital promptly and receive treatment under the guidance of a doctor.

1. Environmental factors: Changes in seasons or substances in the air such as pollen and dust mites can irritate the nasal mucosa, causing sneezing and a runny nose. It is recommended to avoid contact with known allergens or irritants as much as possible and to use air purifiers to clean indoor air.

2. Cold air irritation: In cold climates or when suddenly entering an air-conditioned room, the nasal passages may be irritated by cold air, causing nasal mucosa contraction, which can lead to sneezing and a runny nose. It is recommended to keep warm, avoid sudden exposure to cold environments, and avoid prolonged exposure to cold air.

3. Allergies: Allergens such as pollen, dust, and animal fur can irritate the nasal mucosa, leading to frequent sneezing and a runny nose, which may be accompanied by nasal itching, congestion, and reduced sense of smell. Patients can take medications such as cetirizine hydrochloride tablets, loratadine tablets, and ephedrine diphenhydramine tablets under a doctor's guidance to alleviate symptoms.

4. Common cold: The common cold is an acute upper respiratory infection caused by various viruses, which leads to local inflammatory responses, nasal mucosa congestion, and increased secretions, manifesting as sneezing and a runny nose. Symptoms may also include fever, headache, muscle pain, and cough. It is recommended to take antiviral oral liquid, Lianhua Qingwen capsules, Ganmaoling granules, and other medications as directed by a physician.

5. Sinusitis: Sinusitis refers to the inflammation of the nasal sinus mucosa, often caused by bacterial or fungal infections. Blockage of the sinus openings prevents secretions from draining normally, causing fluid to accumulate in the sinuses, which irritates nasal receptors, resulting in sneezing and a runny nose. This may be accompanied by facial pressure, headache, and reduced sense of smell. Patients can take medications such as roxithromycin tablets, cephalexin dry suspension, and clindamycin hydrochloride tablets under the guidance of a doctor to alleviate symptoms.

In daily life, maintaining good indoor air circulation, avoiding allergens, staying well-hydrated, and maintaining healthy lifestyle habits can help prevent these symptoms.
