Thanks for your question on Health Care Magic.
I can understand your situation and problem.
In my opinion, you should definitely
consult pulmonologist.
Following are the possibilities in your case.
1. Worsening of
bronchitis.
2. Worsening of lung mass (enlargement)
3.
Pulmonary embolism.
So you need repeat PFT, CT
Pulmonary Angiography.
PFT will tell you about severity of bronchitis. According to the severity, you may need additional bronchodilators.
CT Pulmonary Angiography will diagnose Pulmonary embolism if present.
It will also tell you about size of the tumour whether increased or not.
So better to consult pulmonologist as soon as possible and discuss all these.
Hope I have solved your query.
Wish you good health. Thanks.
