Thanks for your question on Healthcare Magic.
I can understand your concern.
Your all symptoms are suggestive of heart and lung related diseases.
Heart diseases like ischemic heart diseases,
heart failure etc can cause similar symptoms. Lung disease like
bronchitis can cause similar symptoms.
So better to
consult doctor and get done
1. Blood pressure monitoring, ecg, 2d echo and
stress test (trade mill 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 sometimes stress and
anxiety can also cause similar symptoms.
So avoid stress and tension, be relax and calm.
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.
