Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Yes, you should definitely
consult pulmonologist.
Your symptoms like cough, breathlessness,
chest pain are commonly seen in
bronchitis. You are also having reddish sputum (blood mixed) and positive family history of
lung cancer, so lung cancer should also be ruled out.
So better to consult pulmonologist and get done
1. Clinical examination of respiratory system
2. Chest x ray
3. PFT (Pulmonary Function Test).
Chest x ray is needed to rule out
lung infection, lung cancer.
PFT is must for the diagnosis of bronchitis.
It will also tell you about severity of the disease and treatment of bronchitis is based on severity only.
You may need inhaled bronchodilators and inhaled corticosteroid.
Don't worry, you will be alright, first diagnose yourself and then start appropriate treatment.
Hope I have solved your query. Wish you good health. Thanks.
