PATIENT PRESENTATION

Chief Complaint

“I’m having pain in my leg.”

HPI

Rodney Cross is a 51-year-old Caucasian man who presents to his primary care physician because of pain in his right leg. He states that he awoke with the pain 3 days ago and that it has been continuous, although it hurts more when he walks. The pain is located behind his right knee and extends down into his calf. He rates the pain intensity as 3/10 at this time. The patient denies CP and SOB. He denies recent travel, immobility, and leg injury. The patient did start atorvastatin 40 mg daily for treatment of dyslipidemia approximately 3 months prior to this visit. He stopped the atorvastatin 3 days ago because he thought it might be causing his leg pain, but the pain has continued.
