Thanks for your question on Health Care Magic.
I can understand your concern.
You are having
hemoptysis (blood in sputum) with chest heaviness and tightness.
All these are commonly seen in
bronchitis,
lung infection and
lung cancer.
So better to
consult pulmonologist and get done clinical examination of respiratory system, chest x ray and PFT (Pulmonary Function Test).
Chest x ray is needed to rule out lung infection and cancer.
PFT is must for the diagnosis of bronchitis.
You may need to, inhaled bronchodilators and inhaled corticosteroid.
Quit smoking if you are smoker.
Don't worry, you will be alright. But first diagnose yourself and then start appropriate treatment.
Hope I have solved your query.
Wish you good health. Thanks.
