What is the reason why you always have a runny nose without catching a cold?

In addition to having a runny nose when you have a cold, some people also have a runny nose when they have the following diseases. Medically speaking, our runny nose will be called runny nose, and a person's runny nose will also be caused by allergies to things. According to the American Foundation, allergies are people's immune responses to substances, such as some pollen and dust, which can cause people to have a runny nose and itchy eyes. If the drug is ineffective, we should go to the hospital for examination and ask the doctor to fill it, which will be good for our nose, but the common cold will also have a runny nose and a stuffy nose and headache. If you catch a cold the next day, it will be more serious on the third day. If this situation lasts for two weeks, we can cure the cold ourselves without treatment, because according to the prevention and control, the cold will be very serious. For better, you should drink more water. In this way, your immune system will also send some ingredients to the disease, kill the bacteria, and you will be cured. There will be a runny nose caused by sinusitis, and a runny nose can't keep sinusitis. Because of sinusitis, its bacterial development will also infect bacteria. For example, many people will get sinusitis after catching a cold. Besides a runny nose, there will be a cold. Medical people say that sinusitis is also caused by bacteria, because some antibiotics are given. If a person's sinusitis is caused by a virus, then he should rest more at home, so as to prevent infection. It may also be caused by non-neurological rhinitis. Non-allergic rhinitis can also cause some allergic phenomena, such as sneezing. Non-allergic rhinitis can also cause damage to your nose due to the erosion of bacteria and the role of cigarettes when your nose is exposed to the surface, or cause rhinitis to people exposed to cold air. Drug treatment can basically cure rhinitis, so we must treat it quickly. When we have a runny nose, we can use drugs to relieve it a little. If we are allergic to cats, we should also have injections. If it is rhinitis caused by a cold, take more rest. Snoring is also common. This symptom may be caused by irritating our noses, so it is also important to protect our noses.
