My father is feeling fatigue, lost appetite, and lost sleep. We have visited multiple doctors. Being diabetic, we suspected diabetic neuropathy and visited a neurologist. As part of tests, he has taken X-ray also and identified pleural effusion and referred to a pulmonologist with HRCT scan of lungs and GeneXpert sputum. Pulmonologist suggested AFB smear also. HRCT shows effusion, but AFB smear and GeneXpert are negative.
