For a week, I've had a cold. However, my nasal secretions have been yellowish and smelly since today. What should I do?

It is recommended to use nasal hygiene techniques, such as Sinus Rinse™ twice a day for at least 5 days. This can help clear the sinuses and nasal passages of thick secretions, possibly reducing the risk of sinusitis. If symptoms persist after 5 days, it is advised to consult a doctor.
