Patient Zhang often watched some health TV programs, and once he watched a lecture on nasopharyngeal cancer and remembered that his nose was very dry in recent times, and occasionally there was blood in his nasal mucosa. I gave him some peppermint camphor paraffin oil and he was fine soon. In fact, this situation is very common among elderly people, because the glandular secretion function of the elderly decreases, resulting in dry nasal mucosa, and when blowing the nose, the small blood vessels of the mucosa are prone to rupture, so there will be blood in the snot, especially in the autumn and winter seasons will be more common, so in addition to the living environment to keep moist, but also often keep the nasal cavity moist, such as drops of saline into the nose, or before going to bed with wet cotton balls Loosely plugged in the front nostrils, can effectively relieve the symptoms. Of course, if the treatment is ineffective or the symptoms worsen, you need to go to the hospital to check the fiberoptic nasopharyngoscope, you need to rule out whether there are other lesions in the nasal cavity or nasopharynx, because some diseases such as nasopharyngeal carcinoma early symptoms are also blood in the snot, so we should not take it lightly.
