Dear doctor, a three months ago I have undergone a cardio test all were perfect then. But now I have experienced a severe and acute chest pain that is back side of lower rib cage and it has been deviating to my chest’s back side for a week ago. It happens simultaneously while I am awakening at that time I have a tendency to pull in warm speedy breathes automatically. Just last 3-6 hours I felt so, I would like to know the root cause of this can you help me? Thanks!
