Scar tissue of the lungs is not a disease. It is the tissue that can substitute normal lung tissue that suffered an inflammatory injury, as result of a severe infection for exemple. Some diseases are difficult to diagnosis and sometimes clinical symptoms, signs and tests findings may be inconclusive or misleading. A strong relationship of trust with your physicians is extremely important to overcome the challenges of your treatment and rehabiltation. Your physicians will not hide from you anything related to your condition if openly questioned about it. The anxiety in the presence of a condition that is not completly understood or that does not improve may sometimes leads us to look for opinions of many different specialists. However, this conduct can also cause prejudice as sometimes it is difficult to stabilish and follow a sequence to diagnosis and treatment. Talk to your attending physician, expose all your doubts and questions and if you feel assured that you are been well cared, continue your treatment.
