Patients with redness on both sides of the throat may have congestion and swelling of the tonsils on both sides of the throat, which is a manifestation of acute inflammation of the tonsils, and patients may also have congestion and swelling of the lymphatic tissue of the lateral pharyngeal cord on both sides of the throat, which is often caused by acute inflammation of the throat. Patients often experience a certain degree of swelling and pain in the throat due to these inflammatory factors, and some patients may have adverse effects on normal swallowing and eating when the degree is severe. Patients may suffer from cold or flu, or use their voices too much, smoke too much, drink too much, eat spicy and stimulating foods, which may easily cause congestion and swelling of both tonsils and lymphatic tissues on both sides.
