History of Present Illness
A 26-year-old male firefighter presents to his PCP following an ED visit for an episode of dehydration and severe muscle pain experienced during rigorous physical activity. Yesterday, he fought a fire for an extended period under extreme physical conditions. Despite consuming significant amounts of water, he began feeling lightheaded, experienced severe pain in his calves and shoulders, and noticed dark-colored urine. He was evaluated in the ED and discharged with instructions to hydrate. However, he continues to have dark-colored urine, generalized muscle pain, and fatigue. He reports feeling “like I’ve been hit by a truck.”

CLINICAL DISCUSSION
Based on the subjective and objective information presented, select and prioritize three differential diagnoses, including each diagnosis’s rationale, pathophysiology, and pertinent positives and negatives.
For the working diagnosis, explain why this is the primary diagnosis, what physical findings support the primary diagnosis, and list any additional body systems not addressed in the physical exam and how those physical findings could further support your primary diagnosis.
• List any additional questions you may have inquired about in your history taking that have not already been presented in the HPI and are necessary to establish your diagnosis.
• Address any necessary laboratory or diagnostic testing and the clinical significance of these diagnostics for your diagnosis or ultimate treatment plan.
• Discuss the next appropriate steps in your management and at least two potential complications of this diagnosis untreated.
• Finally, discuss medication management, including pharmacologic and nonpharmacologic choices with appropriate dosing, comprehensive patient education, and follow-up recommendations
