A cold generally can cause symptoms of sore throat, due to conditions like pharyngitis or tonsillitis triggered by the cold. Typically, the illness lasts about five to seven days, partly due to a decrease in immune strength, which is somewhat related to the low resistance. During this time, it is important to rest sufficiently, stay hydrated, and avoid excessive fatigue. In severe cases, it may also be necessary to use anti-inflammatory and anti-infection medications as well as cold remedies under a doctor's guidance to alleviate symptoms. Furthermore, if a sore throat occurs immediately with a cold, it might indicate chronic pharyngitis; it is advisable to use medications regularly and in the correct dosage under a doctor's guidance to prevent worsening of the condition. Additionally, drinking herbal teas that clear heat and detoxify can also provide some relief.
