Which option is NOT a symptom of rhabdomyolysis?

• A. Joint swelling with redness
• B. Generalized muscle pain, nausea and vomiting, abdominal cramping, and dark-red urine
• C. Dark urine due to myoglobin
• D. Nausea and vomiting

Answer: (B)

Rhabdomyolysis presents primarily with signs of muscle injury and systemic effects from muscle breakdown. Muscle pain, swelling, and weakness are common, and the release of myoglobin from damaged muscle can color the urine dark or reddish. Nausea, vomiting, and abdominal cramps can accompany the condition as the body deals with the breakdown products and potential kidney strain. What isn’t typical is joint swelling with redness. Joints aren’t the primary site affected in rhabdomyolysis, so swelling and redness of a joint points more toward a joint-specific issue rather than muscle breakdown. So, the statement describing joint swelling with redness is not a symptom of rhabdomyolysis, while the other options describe signs that can occur with it.
