Chest and abdominal pain can be caused by overstrain of the respiratory muscles, intercostal muscles, or spasms of the abdominal muscles. It is often confused with heart problems or problems with internal organs, but in many cases it is related to muscle dysfunctions. The clip places this within “Muscular pains in the chest and abdomen” so it is easier to understand what is happening in the area, not only where symptoms are felt.
