My father aged 80 years has undergone pleural tapping with fluid report as attached. Is  major procedure as tharacoscopy the next immediate step ? I am told medication for tuberculosis has begun. After almost one week of this medication , breathlessness has reduced but coughing troubles him at night primarily.  Use of inhaler is minimal close to 1-2 times per 24 hrs. all cardiac tests like echo, ecg done with no issues .Plz reply. regards.
