Muscle Pain

Active or inactive, muscle pain can affect us all

The most common causes of muscle pain are tension, stress, over use and minor injuries. This type of pain is usually localized, affecting just a few muscles or a small part of your body.

Systemic muscle pain — pain throughout your whole body — is more often the result of an infection, an illness or a side effect of a medication.

It’s normal to have sore muscles after you work out, play sports, or even do housework, especially if:

  • You did something you’re not used to, like running a marathon when you normally jog just a few miles.

  • You suddenly kicked up your exercise intensity level or increased the length of your workout.
