How to Tell if It’s Just a Cold or a Sinus Infection Colds and sinus infections can feel similar at first, but there are key differences to watch for: ✅ Duration – A common cold usually clears up within 7-10 days. If your symptoms persist beyond 10 days or worsen after initially improving, it might be a sinus infection. ✅ Facial Discomfort – Sinus infections often cause intense pressure or pain around your eyes, forehead, cheeks, and even upper teeth — something a cold rarely does. ✅ Nasal Discharge – While colds produce clear or slightly cloudy mucus, sinus infections usually cause thick, yellowish or green mucus. #healthcare tips #healthcare #NMC #hospital
