HI, thanks for using healthcare magic
Chest pain can occur with problems in any area of the chest from the skin inwards- skin, muscles, bones, heart, lungs,
esophagus. It can also be due to anxiety.
Any
severe pain can be associated with hard time breathing.
The most common worry in persons with chest pain is
heart disease but this is not usually associated with
back pain.
The doctors in the ER may have done tests such as EKG, to take a look at the heart.
They have also done a chest x ray to take a look at the lungs.
These tests would have ruled out heart and lung disease.
If the pain continues with no relief from the medication prescribed, then you may need see your doctor for re assessment.
I hope this helps
