ABSTRACT
SUMMARY: A 21-year-old healthy Korean man worked on a building construction site every day for almost 2 months and exercised every day for 1 or 2 hours after working hard. He felt dizziness, nausea, and experienced vomiting and body aches immediately after exercise and immediately took cold medicines including acetaminophen, cimetidine, bepotastine, and Codenal? complex for the common cold symptoms for 2 days because he was scheduled to participate in navy training at that time. He complained of severe trapezius pain and aches in his left calf 3 days after joining the Navy training. Testing revealed creatine phosphokinase (CPK) 6260 U/L, myogloblin 176 mcg/L in the urine, liver enzymes increased, and oliguria, suggesting rhabdomyolysis. He recovered with intravenous fluids without any complications.
