What is the cause of the incessant sneezing?

Non-stop sneezing is a reaction of the nasal mucosa after being stimulated, which may be caused by allergic rhinitis, acute rhinitis or vasomotor rhinitis.
1. Allergic rhinitis: When allergens, such as pollen, enter the nasal cavity and stimulate the allergic reaction of the nasal mucosa, the common symptom is continuous sneezing, which is one of the most common causes of sneezing.
2. Acute rhinitis: when the patient has a cold, the symptoms of acute rhinitis will appear, such as sneezing, nasal congestion, runny nose, etc. Most of the causes of acute rhinitis are viral and bacterial infections.
3. Vasomotor rhinitis: this kind of sneezing originates from the phenomenon of increased excitability of the parasympathetic nerves in the nose and high reaction to changes in humidity and temperature, even spicy food.
If you feel unwell, you should go to the hospital in time for systematic examination and diagnosis, so as to avoid delaying your condition or triggering adverse reactions.
