My mother is having chest pain since January 2017 till date. All the blood test i.e. CBC, LFT, KFT, E CG, Ultrasound ABDN, Thyroid are negative, except X-ray which shows infection in the left lung. CT scan states that upper left lobe is collapsed. No heart problem, no sugar problem and no BP problem. There is no finding in the Bronchoscopy. AFB Negative, Sputum Negative but X-ray shows infection is increasing. Based on the recommendation of the Doctor medicine i.e. Macox Plus, Pyzinia 1000, Combutol 800 & Durapain are being taken since last two months. Chest Pain is little bit decreasing occasionally and as per the infection in lung is increasing as come to know in the X-ray done after two months. As of now, my mother is feeling very weakness and also not showing any interest in eating the food. May please suggest any further action if any or wait till medicine respond and to see positiveness in the matter.
