One of the most uncommon causes of upper back pain is when the cartilage that connects your breastbone to your ribs is dealing with an inflammation; this condition is called costochondritis.
This condition can be caused by respiratory infections, chest injuries, and when lifting heavy items. However, the source of pain is often unclear because it travels between your back and chest.
If this is what you are experiencing, then you should be checked by a doctor, but usually, this t this pain fades away without treatment.
