Occasionally cough, feel throat always has phlegm to spit out, have relation with lung infection?

Pulmonary infection refers to a series of diseases caused by various pathogens. However, in clinical practice, most of them refer to pneumonia caused by bacterial infection. Cough is the main symptom of lung disease. If it is a lung infection, sputum should come from the lung, not the throat.

cough occasionally, with phlegm in the throat, but can’t cough out. From the characteristics of this symptom description, it may be pharyngitis, laryngitis, tracheitis, bronchitis, pneumonia, etc. In short, respiratory diseases will appear these symptoms.

these diseases can occur together, but they have their own characteristics. For example, pulmonary infection may be accompanied by shivering, fever, chest pain, shortness of breath, and even cyanosis of lips. In severe cases, there will be some systemic symptoms, such as fatigue, loss of appetite and other discomfort.

if it is tracheitis or bronchitis, the main symptoms are cough, sputum or no sputum, shortness of breath, wheezing when breathing. If you don’t have a stethoscope, you can hear the sound of whistling with your ear close to your back. This is a kind of sound produced when the airflow passes due to the narrow airway.

throat diseases can also lead to coughing. This kind of cough is because the throat part also has some secretion, or itself has inflammation edema, will have the uncomfortable feeling. People will feel that there is phlegm in it, and they also want to clear it by coughing, which is the daily action of clearing their throat.

throat diseases, trachea and bronchitis are mostly developed from upper respiratory tract infection, that is, cold. There will also be cough and fever at the beginning, but the duration of fever is not long, and cough may last for a long time. Some patients have a certain relationship with allergies, allergens from dust or bad air environment.

in case of this situation, if it is more than two weeks, the symptoms are not significantly relieved, or even worse, with afternoon or evening fever, night sweats, weight loss and other manifestations, it is necessary to check whether there is tuberculosis. Sputum smear, sputum culture, blood routine and C-reactive protein are usually needed to find Mycobacterium tuberculosis, which is helpful to determine the source of infection, but it is not the test method to determine the pathogen.

if you cough within two weeks, you can try to use some symptomatic drugs, such as antiallergic drugs and expectorant drugs. If you need to use antibiotics, or there are signs of bacterial infection, you can use some antibiotics for common pathogens, such as azithromycin and so on.

it should be noted that some smokers often have such symptoms. They have phlegm in their throat, and they want to cough but can’t cough. They call this chronic pharyngitis. Examination can see that there are some pharyngeal follicular hyperplasia, mostly due to repeated chronic inflammatory stimulation. After quitting smoking, the symptoms will be relieved, and some people have some psychological factors.

drinking more water, paying attention to rest, avoiding bad air and environment, strengthening nutrition, etc. are some important non drug treatment programs. Although they have no direct therapeutic effect, they can relieve symptoms to a certain extent.

if it’s just a cough and I feel that I can’t cough with phlegm, it’s not enough to judge that I have pulmonary infection. The best way is to do a lung X-ray or CT examination. If the CT radiation is larger, we should decide whether to do blood routine and C-reactive protein examination according to the specific situation, so as to assist in the diagnosis and treatment.
