Jingzhou netizen consultation: I always feel very dry inside my nose these days, especially after getting up in the morning, there is always a dry yellow booger in my nose, which forms a scab. I don't usually have a runny nose. Where can I get so much booger? My nose still hurts. Excuse me, what is this? Could it be rhinitis? Wuhan Ren 'an Eye Otolaryngology Hospital Online Doctor Answer: The nose hurts, generally speaking, it may be caused by inflammation of the nasal cavity. Patients can check whether they have a cold in the near future. If the cold has not healed for a long time, they should pay attention, because the long-term existence of cold inflammation can easily deteriorate into rhinitis. The function of nasal cavity detoxification ensures that bacteria do not exceed the number that the human body can bear. However, if you catch a cold, get wet, get tired, and so on. The detoxification function of the nasal cavity will be reduced and the resistance will be reduced. Bacteria will stay in the nasal cavity for a long time and multiply in large numbers, leading to colds. Cold inflammation exists for a long time, and it will cause rhinitis if it is not cured in time. The booger you are talking about is the inflammatory secretion of rhinitis and nasal mucosa, which adheres to the nasal mucosa wall to protect the damaged nasal mucosa. Of course, the situation you are talking about is not necessarily rhinitis, but may also be caused by environmental factors. For example, the indoor air is not circulating and it is turbid. It may also be caused by excessive internal heat, imbalance of yin and yang, occasional inattention, nasal mucosa damage caused by nose picking, dry nose and continuous secretion of mucus. It will get better in a few days. If you feel uncomfortable, you can refer to "Is it okay to wash your nose with sodium chloride injection?" Washing the nose with salt water can promote recovery. Warm reminder: The rhinitis mentioned above is a general term, including chronic simple rhinitis, sinusitis and allergic rhinitis. Different types of rhinitis have different symptoms.
