Welcome to healthcaremagic.
You've not mentioned your age? Whether you suffer from Diabetes/Blood pressure issue or any other medical issues or not?
Have you consulted any doctor about this problem or not? What treatment has been tried so far?
Breathlessness/acute chest pain
etc are symptoms where examination and certain investigations are necessary before commencing the treatment.
I would advise:
1. To see a Physician
2. Certain investigations may be necessary based on the history and examination findings.
3. Investigations like Chest x-ray, lung function tests, ECG etc may be necessary after physical examination.
I hope I've been able to guide you further in this matter.
