eli5 when you “pull a muscle” what is happening to the muscle that causes it to “pull” and cause severe pain?


Pulled a muscle in my back today, and it really messed my entire day up. So wondering what is happening, and why a pulled muscle doesn’t happen all the time.

You’re either straining or actually tearing the muscle (in a minor fashion). It can happen because of overuse, poor nutrition, or getting older. Tight muscles are much more susceptible, which is why stretching properly before physical activity is important.

In eli5 terms, basically you’ve pushed the muscle past its limits and caused damage to the muscle beyond the micro tears seen with controlled lifting. Obviously damaging the muscle causes pain. Depending on the severity this can be bothersome because anytime the muscle contracts is susceptible to aggravating the pain again
