Thanks for your question on Healthcare Magic.
I can understand your concern.
Chest pain, coughing and breathlessness are commonly seen with heart and lung diseases.
So better to
consult doctor and get done
1. Ecg, 2d echo and
stress test to rule out heart diseases.
2. Clinical examination of respiratory system, chest x ray and PFT (pulmonary function test) to rule out lung diseases.
If all these are normal then no need to worry for heart or lung related diseases.
Sometimes, uncontrolled stress and anxiety can also cause similar symptoms.
So avoid stress and tension, be relax and calm.
Consult psychiatrist and get done
counselling sessions. Try to identify stressor in your life and start working on it's solution. You may need anxiolytic drugs.
Don't worry, you will be alright, but first rule out heart and lung related diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
