Why Sore Throats Can Linger After a Cold

Cepacol®, known for its sore throat lozenges¹, hot medication^2&3, and now a new raspberry-flavoured effervescent⁴, delves into why sore throats can potentially linger after a cold, and how you can potentially find relief.

Postnasal drip

One potential common cause of a lingering sore throat is postnasal drip. Post-nasal drip happens when your nose produces extra mucus that trickles down the back of your throat. This can lead to a cough, sore throat, or the need to clear your throat frequently.⁵ After a cold, your body may continue to produce excess mucus to flush out remaining pathogens.⁶

Inflammation

A viral infection, which could cause your cold, can lead to inflammation in your throat. Even after the virus is gone, this inflammation can take time to subside, causing ongoing discomfort.⁷

Dry Air

Dry air, especially during the chilly months when indoor heating is used, can dry out your throat, exacerbating throat irritation, soreness, and coughing.⁸

Secondary Infections

In some cases, a secondary bacterial infection such as streptococcus can develop after a viral cold, leading to red and swollen tonsils, sometimes with white patches or streaks of pus, tiny red spots on the area at the back of the roof of the mouth, and painful swallowing.⁹  If your sore throat persists or worsens, it’s important to consult a healthcare professional.
