Thanks for your question on Health Care Magic.
I can understand your situation and problem.
In my opinion you should first
consult pulmonologist and get done
1. Clinical examination of respiratory system
2. PFT (Pulmonary Function Test).
Bronchitis can cause
chest tightness.
And for diagnosis of bronchitis PFT is must. It will also tell you about severity of the disease. And treatment of bronchitis is based on severity only.
If PFT is normal then no need to worry for bronchitis.
You might be having stress, anxiety and
panic attack induced chest tightness.
So better to
consult psychiatrist and get done counseling sessions, try to identify stressor in your life and start working on its solution.
You might need anxiolytic drugs. Avoid stress and tension. Be relax and calm. Don't worry, you will be alright.
Hope I have solved your query.
I will be happy to help you further.
Wish you good health.
Thanks.
