Sore throat before cold may be related to viral infection, acute pharyngitis, acute tonsillitis.
A sore throat before a cold can be caused by a viral infection. Colds are generally associated with viral infections, and respiratory viral infections first need to pass through the throat. The mucous membrane in the throat area is relatively fragile and can become edematous under the influence of the virus, resulting in a sore throat.
Secondly, it may be related to acute pharyngitis and acute tonsillitis. Bacteria or viruses make the tonsils become infected, then the tonsils become congested and enlarged. This can lead to pain in the throat, which is a normal symptom of enlarged tonsils.
It is recommended that you seek medical attention in time to deal with similar symptoms under the guidance of your doctor.
