Cough and cold: Cold cured, but cough persists? Why does this happen and what measures to take

The cold and cough have been cured, but the stubborn cough is not going away. You might have also had such an experience. However, there is no need to worry about this, it is quite a common thing. According to a study published in the Canadian Medical Association Journal, 11% to 25% of adults suffer from cough after a cold. This cough can last for 3 to 8 weeks.

According to researchers, post-infection cough (also called post-viral cough) can occur after a viral infection. Omid Mehdizadeh, MD, an otolaryngologist (ENT), explains that this cough is caused by increased inflammation in the respiratory system, including the nose, throat, voice box, and lungs. According to studies, this inflammation can increase the sensitivity of the respiratory tubes and increase the process of mucus formation, while at the same time reducing the ability to expel mucus.

Treatment of post-infection cough
Dr. Chantal Strachan, a primary care physician and internist at Columbia University Irvine Medical Center, says one residual effect of the COVID-19 pandemic is the stigma surrounding chronic cough. However, he said that post-infection cough can usually be a matter of concern, but it does not indicate any serious disease.

Dr. Strachan further said that over-the-counter cough syrups, nasal decongestant sprays, humidifiers, and lozenges can prove effective for this cough. He also said that there is no use of antibiotics or steroids in this situation. According to studies, in most cases, cough gets cured with time even without any medicine. The use of medicines can also harm the environment.

When to understand that cough is serious?
Post-infection cough is usually a dry cough. At the same time, an investigation of a cough accompanied by difficulty in breathing or chest pain is necessary. He said that symptoms like bleeding in sputum, difficulty in swallowing, pain, fever, difficulty in breathing, and wheezing while breathing should not be ignored. In case of such symptoms, a chest X-ray may be necessary. If the cough lasts for more than 8 weeks or you notice other serious symptoms, then definitely contact a doctor.
