Mild rhabdomyolysis may have no obvious clinical symptoms, or it may be manifested by pain, change of urine color, elevation of creatine kinase and myoglobin. 1. Pain: Mild rhabdomyolysis may be manifested by acute muscle weakness, pain, tenderness and swelling of the affected limb or body region, sometimes manifested as blisters, superficial pressure sores, etc. 2. Urine color change: hemoglobinuria can be seen in mild rhabdomyolysis, and the urine color becomes darker, presenting as tea color or soy sauce color. 3. Elevated creatine kinase and myoglobin: The common indicators of mild rhabdomyolysis include elevated serum creatine kinase concentration, myoglobin, lactate dehydrogenase, potassium, aminotransferase and other abnormal changes in laboratory indicators. If left untreated, there is a risk of further exacerbation of the condition, with symptoms such as rapid heartbeat, fatigue, fever, and even complications such as acute kidney injury, osteofascial compartment syndrome, and disseminated intravascular coagulation. Patients with rhabdomyolysis syndrome need to be examined and treated in a timely manner to avoid delaying the condition, which may lead to serious adverse consequences.
