In patients with colds, most symptoms found are fever, cough, sneeze and running nose which will get better within a few weeks. If the symptoms become worse, with yellowish-green mucus, it might be sinusitis.
For allergies or allergic rhinitis, the symptoms are the stuffy nose, clear mucus, sneezing, and itchy nose or eyes. It might occur throughout the year, or in a certain period of times, getting better and then occur again. In the rainy season, winter, and nighttime, the symptoms are more prominent than during the day. Allergic rhinitis is a common respiratory infection that caused you catching a cold easily.
In case of having yellowish-green mucus, consulting a doctor for diagnosis is recommended. Stay away from allergic triggers such as dust or smoke. For people with chronic mucus, a nasal wash can help reduce nasal congestion, mucus, and sputum dripping down your throat and highlight the effectiveness of nasal spray.
