Creatine kinase (CK) itself does not cause symptoms. However, elevated CK levels can be indicative of underlying muscle damage or injury. The symptoms experienced are typically related to the specific condition causing the muscle damage. For example, in muscular dystrophy, muscle weakness, muscle wasting, and difficulties with mobility may be observed. In cases of rhabdomyolysis, which involves severe muscle breakdown, symptoms may include muscle pain, swelling, weakness, and dark-colored urine. It is important to consult with a healthcare professional for an accurate diagnosis and to address the underlying condition leading to elevated CK levels. Proper management of the underlying condition can help alleviate symptoms associated with muscle damage.
