In myalgia, the pain can be acute, meaning it lasts a few days and is related to recent injuries or physical activity; but it can also be chronic pain lasting weeks or months, often linked to inflammatory diseases, persistent infections, or nervous system disorders.<\/p>\n

Additionally, this condition may occur locally in a specific muscle or appear diffusely, affecting several muscle groups simultaneously.<\/p>\n

Muscle injuries<\/h2>\n

Muscle injuries are a common cause of myalgia and are mostly related to trauma, overexertion, or engaging in physical activity without proper warm-up.<\/p>\n

Among the most common muscle injuries associated with myalgia is muscle strain, which occurs when muscle fibers stretch beyond their natural limit, causing immediate pain, mild inflammation, and limited movement.<\/p>\n

A muscle tear is a more severe injury in which muscle fibers are partially or completely torn. This causes sharp pain, swelling, and sometimes visible bruising.<\/p>\n

Muscle cramps are involuntary and painful muscle contractions that can last from a few seconds to several minutes.<\/p>\n

Muscle contractures occur when a muscle remains in a continuous state of contraction and are usually the result of overexertion, poor posture, or prolonged emotional tension.<\/p>\n

Although tendinitis directly affects the tendons\u2014structures that connect muscles to bones\u2014it can also cause muscle pain due to the inflammation and tension in the affected area.<\/p>\n

A muscle contusion occurs after a direct blow to a muscle, causing damage to muscle fibers and blood vessels.<\/p>\n
