Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Lung infection and
bronchitis are the most common causes for
cough, expectoration with on - off blood.
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.
PFT is must for the diagnosis of bronchitis.
You may need antibiotics, antihistamines, inhaled bronchodilators and inhaled corticosteroid (ICS).
Don't worry, you will be alright with all these medicines.
Hope I have solved your query.
Wish you good health. Thanks.
