kept coughing for 1 month, took Antibiotic but no help, no fever, no soar throat, just kept feeling inchy in throat and want to cough every moment. Took a Xray on chest yesterday, the statement is :There is mild accentuation of bronchovascular marking, may due to chronic inflammation or bronchitis.What s meaning of this? is it serious? or should I take a CT scan?My GP just let me take medicine as before.Thanks in advance.
