Fever, nasal congestion, dizziness, and sore throat—what's causing this, and what should I do?
Fever refers to an elevated body temperature. Symptoms such as fever, nasal congestion, dizziness, and sore throat may be caused by environmental irritants, overexertion, the common cold, pharyngitis, sinusitis, or other pathological conditions. These can be managed by maintaining appropriate indoor humidity, scheduling rest properly, and using medications. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Detailed analysis is as follows:

1. Environmental irritation: Prolonged exposure to dry or cold environments may lead to dryness and congestion in the nasal passages, resulting in nasal congestion. In addition, uncomfortable environments may also trigger symptoms such as dizziness and fever. It is advisable to maintain suitable indoor humidity and avoid prolonged exposure to cold or dry air. Wearing a mask outdoors helps reduce the inhalation of harmful substances in the air.
2. Overexertion: Extended periods of work or study without adequate rest or sleep may reduce immune function, increasing susceptibility to viral or bacterial infections and leading to the aforementioned symptoms. Patients are advised to arrange their daily schedules reasonably, ensure sufficient sleep and rest, and engage in moderate physical exercise such as running or walking, which can help strengthen the immune system.
3. Common cold: This may be associated with climate changes and viral infections. These factors may allow pathogens to invade the upper respiratory tract, causing inflammation in the nasal and throat areas, manifesting as nasal congestion, sore throat, dizziness, and fever. Additional symptoms may include coughing and runny nose. Patients are advised to take medications such as Yinqiao Jiedu Pills, Antiviral Oral Liquid, or Ganmaoling Granules as directed by a physician.
4. Pharyngitis: This may be related to excessive fatigue and reduced immunity. After onset, inflammatory changes may occur in the pharyngeal mucosa and lymphoid tissues, easily causing pharyngeal congestion and swelling, leading to sore throat and difficulty swallowing. At the same time, it may also cause fever, dizziness, and nasal congestion. Patients are advised to follow medical advice and use medications such as Compound Honeysuckle Granules, Amoxicillin Capsules, or Ribavirin Tablets for treatment.
5. Sinusitis: This is generally caused by abnormal nasal structure, allergies, or other factors. After onset, inflammatory changes in the sinus mucosa commonly occur, potentially increasing nasal secretions and causing discomfort such as nasal congestion and dizziness. Sinusitis may also be accompanied by symptoms like sore throat and fever. Patients should use medications such as Roxithromycin Tablets, Cefalexin Dry Suspension, or Clindamycin Hydrochloride Tablets under a doctor’s supervision to alleviate symptoms.
In daily life, patients are encouraged to drink plenty of warm water, maintain a positive and optimistic mindset, and consume fresh vegetables such as radish, celery, and lettuce appropriately, all of which may benefit recovery.
