Introduction
In general, a persistent sensation of a foreign body in the throat may be caused by a dry throat, pharyngeal muscle tension, chronic pharyngitis, tonsillitis, or reflux laryngitis. To prevent this symptom, it is recommended to avoid spicy, greasy, and irritating foods, and to quit smoking and limit alcohol consumption in daily life. In addition, keep indoor air humidified and avoid staying in dry environments for prolonged periods.

Generally, a persistent sensation of a foreign body in the throat may be caused by dry throat, pharyngeal muscle tension, chronic pharyngitis, tonsillitis, or reflux laryngitis. If discomfort occurs, timely medical consultation is recommended. Detailed explanations are as follows:

1. Dry Throat

Dry throat can reduce moisture on the mucosal surface, causing dryness and sensitivity of the mucosa, thus producing a sensation of a foreign body. Keeping indoor air humidified, drinking more water, and avoiding prolonged talking or loud shouting can help reduce moisture loss from the throat mucosa.

2. Pharyngeal Muscle Tension

Long-term mental stress or anxiety may cause involuntary contraction of the throat muscles, leading to a sensation of a foreign body. Learning to relax, avoiding prolonged tension, and practicing deep breathing appropriately can help relieve pharyngeal muscle tension.

3. Chronic Pharyngitis

Chronic pharyngitis may be caused by recurrent acute pharyngitis, long-term irritation from smoking and alcohol consumption, or dust pollution. Inflammation may cause congestion and edema of the pharyngeal mucosa, resulting in a foreign body sensation. Symptoms may include throat pain, dryness, and burning sensation. Patients should follow medical advice to use medications such as compound borax mouthwash, watermelon frost tablets, and cetidine tablets for treatment.

4. Tonsillitis

Tonsillitis may be caused by bacterial infections such as streptococcus or staphylococcus. Inflamed tonsils may swell and irritate the throat, causing a foreign body sensation. It is usually accompanied by difficulty swallowing, fever, and headache. Patients can take antibiotics such as penicillin V potassium tablets, cefixime capsules, and azithromycin dispersible tablets under a doctor's guidance to eliminate the infection.

5. Reflux Laryngitis

Reflux laryngitis may be caused by stomach acid flowing back into the throat, irritating the mucosa and causing inflammation. Inflammation may damage the mucous membrane, leading to a sensation of a foreign body. Symptoms may also include hoarseness, coughing, and frequent throat clearing. Patients can take medications such as omeprazole enteric-coated capsules, rabeprazole sodium enteric-coated tablets, and domperidone tablets under a doctor's recommendation for treatment.

To prevent this symptom, it is recommended to avoid spicy, greasy, and irritating foods, quit smoking, and limit alcohol consumption in daily life. Additionally, maintaining humid indoor air and avoiding prolonged exposure to dry environments is advised.

Is coughing up phlegm after each nucleic acid test due to an allergy to the throat swab?
During throat swab collection, the swab may rub against the pharyngeal mucosa, causing mild irritation and increased mucosal secretions, which can lead to coughing with sputum. This condition is usually temporary and resolves spontaneously within 1–2 days without other discomfort. However, if coughing with sputum is accompanied by symptoms such as sore throat, redness, swelling, or itching, it may indicate an allergic reaction to the swab material or disinfectant used. Although such cases are uncommon, they require attention.

Does an itchy throat affect the results of nucleic acid testing?
Itchy throat does not affect the results of nucleic acid testing. The core principle of nucleic acid testing is to detect whether the target pathogen's nucleic acid sequence exists in the sample. An itchy throat, usually caused by mucosal irritation or inflammation, does not alter the nucleic acid components in the sample or interfere with the testing process. However, if an itchy throat is accompanied by symptoms such as fever, cough, or worsening sore throat, medical evaluation should be sought promptly to identify the underlying cause.
