What to do about sore throat and swelling after testing positive for COVID-19 the second time

　　"Second infection" generally refers to a second infection with the novel coronavirus. In most cases, sore throat following a second COVID-19 infection can be managed through measures such as drinking plenty of water, resting the voice, avoiding irritating foods and beverages, keeping the throat moist, and medication. Patients are advised to follow medical advice for symptomatic treatment. Specific recommendations are as follows:

　　1. Drink plenty of water

　　Maintaining adequate fluid intake helps alleviate throat pain and promotes the clearance of respiratory secretions. Patients are encouraged to drink more water and may also consume more fruits.

　　2. Rest the voice

　　If experiencing throat swelling or pain, it is important to give the voice adequate rest. Avoid loud talking, shouting, or prolonged speaking, which can help reduce symptoms of throat discomfort.

　　3. Avoid irritating foods and beverages

　　For patients with a sore throat, irritants can worsen pain. It is advisable to avoid spicy foods, acidic foods, coffee, alcohol, and other irritating substances.

　　4. Keep the throat moist

　　Maintaining moisture in the throat is an important step in relieving throat pain. This can be achieved by consuming foods with high water content. Gargling with warm water or using a humidifier to increase indoor humidity may also help.

　　5. Medication

　　Sore throat can be treated with medications such as Qingyan Drop Pills or Shuanghuanglian Oral Liquid, as directed by a healthcare provider. These medications can help relieve throat discomfort and pain.

　　If symptoms persist or worsen, patients should seek timely medical attention for appropriate evaluation and treatment to prevent disease progression.
