If your throat is still sore even though you have recovered from a cold, it may be caused by bad habits, pharyngitis and tonsillitis. 1. Bad habits: Eating too much spicy and stimulating food or staying up too late, using your voice too much and other bad habits can cause a sore throat. 2. Pharyngitis: Pharyngitis may be associated with colds, resulting in inflammation of the pharynx even after the cold is over, which can lead to a sore throat, accompanied by dry, itchy and congested pharynx. 3. Tonsillitis: It is possible that the tonsils become inflamed after the cold is cured due to cold or low immunity, etc., which will result in a sore throat after the cold is cured, as well as difficulty in swallowing and breathing. When the cold is cured but the throat is still sore, it is recommended to go to the regular hospital in time for examination and follow the doctor’s instructions for treatment.
