Thanks for your question on Health Care Magic. I can understand your concern. Pneumonitis is inflammation of lung tissue. Tuberculosis is infection of lungs with tubercular bacilli. So both are different things. Treatment of both is different. And both these conditions can be life threatening if not treated properly. So in my opinion, you should definitely consult pulmonologist and get done 1. Clinical examination of respiratory system 2. Repeat chest x ray 3. CT thorax with Contrast. Better to first diagnose yourself and then start appropriate treatment. Both these are treatable conditions, so don t worry, with proper treatment you will be alright. Hope I have solved your query. Wish you good health. Thanks.
