What causes forehead pain when rinsing the nose?

Under normal circumstances, nasal irrigation causing forehead pain may be due to nasal anatomical structure, irritation from the rinse solution, improper rinsing technique, sinusitis, hypertension, or other factors. If discomfort occurs, it is recommended to seek medical attention promptly. The specific causes are analyzed as follows:

1. Nasal Anatomical Structure

The nasal cavity is connected to paranasal sinuses such as the frontal and ethmoid sinuses. Excessive water pressure during nasal irrigation may force liquid into these sinus cavities, stimulating nerve endings and causing forehead pain. Adjusting the water pressure of the nasal irrigator and using a gentle saline solution can help prevent excessive pressure.

2. Irritation from Rinse Solution

The temperature or composition of the rinse solution may irritate nasal blood vessels, leading to vasoconstriction or vasodilation, which in turn triggers forehead pain. This effect may be more pronounced if the solution is too cold or too hot. It is advisable to adjust the solution temperature to a comfortable range and check whether its ingredients are suitable for individual use. If symptoms persist, consider changing the solution or consulting a doctor.

3. Improper Rinsing Technique

During nasal irrigation, excessive force or incorrect technique may cause sudden changes in nasal pressure, resulting in forehead pain. Discontinue rinsing temporarily and adjust the pressure, ensuring gentle movements and adherence to proper technique.

4. Sinusitis

Sinusitis is caused by viral, bacterial, or fungal infections, often leading to accumulation of secretions within the sinuses. During irrigation, fluid pressure may push against facial nerve endings, causing forehead pain. Symptoms may also include nasal congestion and fever. Under medical guidance, patients may take medications such as Tongqiao Biyan tablets, Biyuanshu oral liquid, or amoxicillin capsules for treatment.

5. Hypertension

Hypertension is commonly associated with aging and other factors. For individuals with high blood pressure, nasal irrigation may induce stress or other responses that elevate blood pressure, leading to headaches and forehead pain, possibly accompanied by dizziness and palpitations. Under medical supervision, antihypertensive medications such as amlodipine besylate tablets, losartan potassium tablets, or metoprolol tartrate tablets may be used for management.

In daily practice, care should be taken to control the force and angle of irrigation, avoiding direct spraying toward the upper part of the nasal cavity. Gentle handling and awareness of personal tolerance are essential.
