What causes itching on the roof of the mouth and nose?

Nasal and upper palate itching is usually caused by allergic rhinitis, vasomotor rhinitis, sinusitis, or other reasons. The exact cause requires a detailed examination at a hospital, followed by targeted treatment. Specific causes are as follows:

1. Allergic Rhinitis

This is mainly triggered by exposure to allergens, leading to symptoms such as nasal pain and dryness. Localized inflammation may stimulate the nasal cavity, causing a crawling or tingling sensation (like ants moving). Treatment may include loratadine tablets, chlorpheniramine maleate tablets, or levocetirizine hydrochloride tablets, taken according to medical advice.

2. Vasomotor Rhinitis

This often results from hormonal imbalances or excessively dry weather, causing symptoms like nasal congestion and runny nose. Inflammation in the area can lead to a foreign-body sensation in the nasal mucosa. Medications such as ketotifen fumarate tablets, fluticasone propionate nasal spray, or mometasone furoate nasal spray may be used as directed by a physician.

3. Sinusitis

This typically occurs due to bacterial infection in the nasal cavity. Local inflammation may cause spasms in the nasal muscles, resulting in an itchy sensation. Treatment may involve antibiotics such as levofloxacin hydrochloride tablets, amoxicillin capsules, or amoxicillin-clavulanate potassium tablets, taken under medical guidance.

Besides the above conditions, chronic pharyngitis, nasal polyps, or nasal tumors could also be potential causes. Treatment options may include medications like ciprofloxacin hydrochloride tablets. During treatment, maintaining good nasal hygiene is essential. If symptoms worsen, prompt medical evaluation is necessary, and patients should cooperate with doctors to receive appropriate treatment.
