Severe Muscle Pain or Dark Urine After Heat: Seek Immediate Care
Odor & SweatArticlePossible rhabdomyolysis needs assessment, even when only one symptom is present.
Stop activity and seek immediate care at the nearest medical facility for muscle pain more severe than expected, tea- or cola-colored urine, or unusual weakness or tiredness that prevents familiar tasks or exercise. NIOSH identifies these as possible rhabdomyolysis symptoms. Do not wait for every symptom to appear.1
Heat and exertion belong in the conversation
Rhabdomyolysis, sometimes called rhabdo, involves damaged muscle releasing proteins and electrolytes into the blood. Heat exposure and physical exertion are workplace risk factors. It can happen after activities you have previously done without a problem.1
A urine color cannot establish the cause
Symptoms can resemble dehydration or other heat-related illnesses. A healthcare provider needs to assess the cause; blood tests for creatine kinase can help identify muscle damage. Drinking water does not replace immediate assessment.1
Tell the medical team what activity you were doing, the heat exposure and the symptoms you noticed. Follow its instructions about testing and further care.1
