My mother was having a coughing symptom for last 8 months. We went to doctor he told us to take a chest CT scan. But the report for sputum came out negative but for sputum for genexpert came positive. We were told to give her akurit 4 for 4 tablets in empty stomach. But sometimes she is experiencing shortness of breathing will it cure. As it was found there was a cavity in the lung will it heal itself and recover on its own. Please guide
