History of Present Illness (HPI)

accompanied by fatigue.

though occasionally produces a small amount of clear sputum.
• The patient experienced mild fever for two days at onset, which resolved without treatment.
• He denies hemoptysis, chest pain, significant sputum production, or weight loss.
• The cough is sometimes worse at night and occasionally disturbs his sleep.
• He notes mild shortness of breath when climbing stairs but denies wheezing at rest.
• He has tried over-the-counter cough syrup and paracetamol with limited relief.
• His roommate had a cold about two weeks ago, which preceded the onset of his symptoms.
• The patient occasionally vapes (3–4 times per week) and owns a cat, which has sometimes
caused mild nasal congestion.
