The most common causes of muscle pain are tension, stress, overuse and minor injuries. This type of pain is usually localized, affecting just one or more muscles or parts of your body. Systemic muscle pain, which you feel throughout your body, is different. It's more often the result of an infection, an illness or a side effect of a medication.
