Thanks for your question on Health Care Magic.
I can understand your situation and problem.
Chronic bronchitis is progressive, incurable disease.
We can only halt the progression, but we can not cure it completely.
Till date no such injection is available. So don't follow this kind of rumours.
Inhaled bronchodilators and inhaled corticosteroid (ICS) are cornerstone of treatment.
You should also enroll yourself in
Pulmonary Rehabilitation center where
chest physiotherapy and deep breathing exercises are done. These will improve your lung function and reduce symptoms.
Get done adult Pulmonary vaccination with pneumococcal and Influenza vaccines to prevent recurrent
respiratory tract infection.
Low dose
oxygen therapy (LTOT) is also beneficial.
So
consult pulmonologist and discuss all these therapeutic options.
Hope I have solved your query.
Wish you good health. Thanks.
