What Could Be the Causes of Pain in the Middle of the Back?

There are instances where back pain is caused by the muscles or bones around the back, and cases where the cause is caused by deeper internal organs.

Muscle and bone problems

Achy muscles or bones can be a result of injury, overexertion, or long-term wear-and-tear.

Internal organs near the back

Issues with the stomach (ulcer, acid reflux), pancreas (inflammation), kidneys (stones, infection), or aorta can also lead to pain in the middle of the back. For example, in a disease called an aortic aneurysm, the aorta swells like a lump. This leads to pressure on the middle of the back and causes pain when it becomes large or is about to burst. This is very uncommon in young, healthy populations but should be considered in older people or those with many cardiovascular risk factors.
