What is an intercostal muscle spasm?

Answer

Intercostal muscles are groups of muscles that are between the ribs. These muscles are used to help the chest wall move, which is essential during breathing. These muscles, like others within the body, can have spasms. This can occur for a number of reasons. Often, intercostal muscle spams may be caused by anxiety. At other times, these types of spasms can be the sign of a heart attack. Anyone experiencing prolonged, painful intercostal muscle spasms will need to visit a doctor to have the issue diagnosed and treated.
