Not necessarily. If the symptoms are mild, you can enhance your diet and nutrition, pay attention to the regularity of work and rest, and pay attention to keeping warm during the change of seasons and increase or decrease clothing at the right time to strengthen your immunity and prevent getting cold, so as to see if the symptoms can be relieved or even disappear. If the symptoms are severe and recurring, you need to go to the hospital, conduct relevant pathogenic and allergen testing, and provide the doctor with a detailed medical history or allergen exposure history. At this point, the doctor can make a comprehensive assessment to rule out similar diseases and make a definitive diagnosis to give the patient the most appropriate treatment.
