A tingling sensation on the tip of the tongue occurs every night.

Generally, tingling or numbness at the tip of the tongue at night may be caused by physiological factors, or it could result from pathological conditions such as allergies or facial nerve paralysis. Targeted treatment should be based on the specific underlying cause. The detailed analysis is as follows:

1. Physiological Factors

If one has poor dietary habits and frequently consumes spicy or irritating foods at night, these can stimulate the tip of the tongue, causing localized numbness. This is considered a normal phenomenon and usually resolves after improving the diet. Generally, there is no need for concern.

2. Pathological Factors

1) Allergies

In individuals with sensitive constitutions, allergic reactions to cold air or dust at night may lead to numbness at the tip of the tongue, often accompanied by local rashes, itching, and other symptoms. In such cases, medications such as loratadine tablets or levocetirizine hydrochloride tablets should be taken under medical supervision.

2) Facial Nerve Paralysis

This condition is commonly associated with exposure to cold or infections at night, which may irritate the trigeminal nerve or glossopharyngeal nerve, resulting in tongue tip numbness. It is often accompanied by symptoms such as drooping of the mouth corner and drooling. Patients are generally advised to take medications such as dexamethasone tablets or mecobalamin tablets under a doctor's guidance.

Besides the common causes mentioned above, other potential factors include cerebral ischemia, cerebral infarction, or local tumors. Patients should seek timely medical attention to avoid delays in diagnosis and treatment.
