If you have a dry cough but your throat doesn't hurt, itch, or have a fever, will it be pneumonia?
A recent onset of dry cough but no sore throat, no itching, and no fever may be due to a noninfectious cause or may be related to an infectious cause. If the above conditions are ruled out, it is considered allergic cough.
1. Non-infectious factors
1. Drug stimulation: For example, long-term use of anti-platelet aggregation drugs such as aspirin enteric-coated tablets or painkillers such as ibuprofen sustained-release capsules, as well as glucocorticoid drugs, such as dexamethasone sodium phosphate injection, etc., can cause certain damage to the throat mucosa, resulting in dry cough symptoms in patients;
2. Foreign body inhalation: If the patient accidentally sticks fish bones or chicken bones into the throat when eating, it will also trigger local inflammatory reactions, which will induce dry cough.
2. Infectious factors
1. Bacterial infection: When the body's resistance is reduced, it is easy to be invaded by bacteria and develop the disease, at this time, the bacteria will multiply in large numbers in the body and release toxins, which will make the respiratory mucosa congested and edematous, and even secrete inflammatory substances, so there will be a dry cough;
2. Viral infection: common in influenza virus and coronavirus, both viruses can cause upper respiratory tract infection, cause inflammation of the nasal cavity and pharyngeal isthmus, and then lead to throat discomfort, accompanied by fever, fatigue and other symptoms.
3. Allergic cough
Some people will be allergic to pollen, dust mites, animal dander, etc., and may have allergic reactions after exposure, manifested as dry cough without phlegm, chest tightness and shortness of breath and other symptoms.
It is recommended that people with this phenomenon go to the respiratory medicine department of the hospital for treatment in time, improve blood routine examination, pulmonary function test and other related examinations, and follow the doctor's instructions for targeted treatment after a clear diagnosis. In daily life, you should avoid eating spicy and stimulating food, pay attention to a light diet, eat more fresh fruits and vegetables, exercise appropriately, and enhance your physical fitness.
