What causes tonsillitis without fever but with dizziness, and what should be done about it?

Under normal circumstances, tonsillitis without fever but accompanied by dizziness may be caused by overexertion, insufficient water intake, acute simple tonsillitis, acute exacerbation of chronic tonsillitis, or peritonsillar inflammation. Depending on the specific situation, symptoms can be improved through general care, medication, surgical treatment, etc. A detailed analysis is as follows:

1. Overexertion

Long-term sleep deprivation or physical exhaustion can reduce the body's resistance, triggering tonsillar inflammation, while insufficient blood and oxygen supply to the brain leads to dizziness. Immediately stop strenuous physical activity, ensure 7–8 hours of sleep daily, and soak feet in warm water before bedtime to relieve fatigue.

2. Insufficient Water Intake

Inadequate fluid intake causes dryness of the pharyngeal mucosa, making the tonsils more susceptible to irritation and inflammation. Increased blood viscosity also affects cerebral circulation. Drink 1500–2000 mL of lukewarm water daily, and avoid stimulating beverages such as strong tea and coffee.

3. Acute Simple Tonsillitis

Viral infection causes congestion and swelling of the tonsils; inflammatory factors spread and lead to dizziness. Fever may be absent when symptoms are mild. Under medical guidance, take Pudilan Anti-inflammatory Oral Liquid, Ribavirin Granules, or Compound Borax Mouthwash. Maintain a liquid-based diet.

4. Acute Exacerbation of Chronic Tonsillitis

Bacteria lingering in the tonsillar crypts become acutely activated after fatigue, leading to recurrent inflammation and resulting dizziness. Take Cefaclor sustained-release tablets, Amoxicillin capsules, or Yinhuang Throat Lozenges as prescribed. Rinse mouth with warm saline after meals to maintain oral hygiene.

5. Peritonsillar Inflammation

Tonsillar inflammation spreads to surrounding tissues, forming inflammatory infiltration that compresses nearby nerves and blood vessels, causing dizziness. Medical treatment is required, possibly including incision and drainage for abscesses. After surgery, take Metronidazole tablets, Clindamycin capsules, and Ibuprofen sustained-release tablets, and avoid severe coughing.

Maintain regular daily routines and avoid excessive fatigue. Eat light, easily digestible food and consume more fresh fruits and vegetables to supplement vitamins. Pay attention to oral hygiene—brush teeth twice daily and rinse mouth after meals. Seek timely medical evaluation and treatment if dizziness worsens or tonsillitis recurs frequently.
