Hi wdlcome toHCMForum. it appears that the cough
might be due to failure of alveolar system to clear the mucous out due to previous 2 attacs of pneumonia
. primarily you should get it treated as there is already infection.
I advise you to consult a physian for diagnosis and treatment. you may have to get the degetal xray and sputum for AFB along with other routine tests for confermation of the disease.
Besides i advise you some diet recomendations as avoid taking brinjal sea foods and any thing you are allergic. take more of green leafy vegetables pulses sprouts egg and meat to build up resistance.wishing for a quick recovery.
thanks for calling.
