In the clinic, there are often patients who say they often have colds, sometimes several times a day, and often take some cold medicine, sometimes good, sometimes useless, very distressed. I learned through careful inquiry that, in fact, what he had was allergic rhinitis, not a cold. Below, I would like to introduce the difference between cold and rhinitis so that patients can have a clear understanding and do not miss the treatment. Cold is the name of a disease in Chinese medicine, which is equivalent to acute upper respiratory tract infection in current medicine, mostly viral, with symptoms such as runny nose, sneezing, headache, sore throat, even general pain, chills, fever, etc. Allergic rhinitis, on the other hand, also has a runny nose, sneezing, and even throat discomfort, or headache as well. So, how to distinguish between cold and allergic rhinitis? First of all, the symptoms of cold, cold runny nose, sneezing, more moderate and continuous, to put it plainly, the onset of cold nasal symptoms is little by little, slowly aggravated, and in the middle there is no too obvious relief period (generally a day is basically 24 hours of nasal symptoms), runny nose can be very little, can also be a lot (catarrhal, mostly seen with measles and other highly contagious viral infections), sneezing There are usually not many sneezes, usually no more than three sneezes at a time (just an approximate number), mostly accompanied by discomfort, headache, sore throat and other symptoms. The symptoms of allergic rhinitis, allergic rhinitis, runny nose, sneezing is relatively strong and short, just like a summer thunderstorm, come fierce, go sharp, a sudden itchy nose, then sneeze after sneeze, an uncontrollable, followed by a continuous stream of nasal mucus, generally last for half an hour to five or six hours, it is good, and even some noses have nothing, the same as normal But when you encounter some irritating smell, you will have the same symptoms as the previous ones and come back for another round, so some patients say they have cold several times a day. Therefore, when you have the symptoms of runny nose and sneezing, you must not abuse cold medicine on your own, but treat the symptoms according to the disease.
