Your condition is mainly inhalation, burping and cough pain. Generally, there are only two possibilities: one is diaphragm smooth muscle spasm and the other is rib fracture. Try to see if there is any special pain when pressing the ribs. If there is, it is a fracture. Watch. Come on.

Rib injury is often unknown, and sometimes panting can cause rib or intercostal muscle injury. By the way, your condition is actually more likely to be an intercostal muscle strain. Because inhalation hurts, much like intercostal muscle injury. So be careful to press, not only the bones, but also the muscles between the bones. If you find anything particularly painful, it is the damaged place.
