Your symptoms are typical for this season and as age advances, the systemic defenses come down and this causes infections to create trouble. I suggest that you consult a pulmonologist
and take advice. You may not be having any recurrence of your old pneumonia
but owing to the reduced ventilatory capacity following the asthma
, it takes time for the symptoms to subside. Your pain is perhaps a muscle spasm following your incessant cough. You should have steam inhalations, nebulising, pain killer and local analgesic
gel application. Please get further instructions from your doctor. Take care.
