Thanks for your question on Healthcare Magic.
I can understand your concern.
You are having
chest pain and breathing difficulty since long (3 months). New symptom is fluttering sensations.
So we should definitely rule out heart diseases (
arrhythmia - rhythm disturbances in heart) first.
So get done blood pressure monitoring, ecg, 2d echo,
stress test and Holter monitoring (24 hours continuous recording of Ecg).
If all these are normal then no need to worry for arrhythmia or other heart diseases.
Sometimes muscular twitching can also cause similar symptoms.
So apply warm water pad on affected areas.
Take
muscle relaxant drugs.
Don't worry, you will be alright with all these. But first rule out heart diseases.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
