[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. By your symptoms and x-ray finding, following are the possible causes.1. Bacterial pneumonia2. Tuberculosis3. Pleural effusion. So better to consult pulmonologist and get done1. Sputum examination for AFB to rule out tuberculosis2. Sputum culture and sensitivity to find out causative organism for pneumonia.3. Ultrasound examination of chest to rule out pleural effusion.4. Bronchoscopy with BAD (Bronchoalveolar lavage) analysis if sputum production is not there. So infective etiology appears more in your case. Better to consult pulmonologist and first diagnose yourself and start appropriate treatment.
