hi I have been coughing out blood in very small amounts for last three months. I have done my x-ray , HRCT, mycobacterium combo test and a number of blood and sputum tests.All the reports were negative .I have also undergone bronchoscopy out of which fungal infection as well as erythema in the left main bronchus was noted. I have taken forcan-150mg, montec-lc, pause-500,nexpro-rd,macpod-cv,dicynene,patadine and formonide inhaler in last 3 months, but still sometimes I get small amount of blood in my sputum.. What should I do now?
