One-sided tonsil pain with associated ear pain
Generally, pain in one side of the tonsils accompanied by ear pain may be caused by conditions such as tonsillitis, acute pharyngitis, or acute adenoiditis. A detailed analysis is as follows:

1. Dietary Irritation
Frequently consuming spicy or excessively hot food can irritate the tonsils, causing local congestion and pain. This irritation may also affect the nerves in the ear, leading to ear pain. It is recommended to adjust the diet by avoiding spicy or hot foods and instead eating light, vitamin-rich foods such as vegetables and fruits.
2. Dry Air
Dry air can cause moisture loss in the mucous membranes of the throat, making them dry and fragile, which may easily trigger tonsillitis and pain, as well as discomfort in the ears. Using a humidifier to maintain indoor humidity between 40% and 60% can help. Alternatively, placing a bowl of water indoors or increasing intake of water-rich foods may also be beneficial.
3. Tonsillitis
Tonsillitis may result from bacterial infection, leading to congestion and swelling of the tonsils. During an acute episode, the pain may radiate to the ear. Treatment may include medications such as amoxicillin capsules, ampicillin capsules, or roxithromycin dispersible tablets, taken under medical guidance.
4. Acute Pharyngitis
Acute pharyngitis may occur due to viral infection of the pharyngeal mucosa, causing inflammation of the mucosa or submucosal tissues. In severe cases, this inflammation may stimulate the ear region. Treatment options include watermelon frost lozenges, iodine throat tablets, or yin-huang buccal tablets, used under a doctor's supervision.
5. Acute Adenoiditis
Acute adenoiditis may be caused by bacterial infection, with inflammation possibly affecting the Eustachian tube and causing the aforementioned symptoms. Medications such as cefuroxime axetil tablets, cefixime granules, or cefradine capsules may be used under a physician’s advice.
In addition, peritonsillar abscess could also be a possible cause. It is recommended to seek timely medical evaluation and receive appropriate, targeted treatment based on the underlying cause. Maintaining healthy lifestyle habits and avoiding spicy or irritating foods is important to support recovery.
