Diabetic myonecrosis, also known as diabetic muscle infarct, is a rare complication of diabetes mellitus, generally associated with poor glycemic control. It is often difficult to diagnose due to its nonspecific presentation and lack of awareness of the complication. Routine laboratory investigations often do not aid in diagnosis. Magnetic resonance imaging (MRI) may assist in diagnosis but is not routinely ordered due to cost-effectiveness and nonspecific radiologic appearance. Muscle biopsy can provide a definite diagnosis; however, it is often avoided due to its invasiveness. Treatment consists of glycemic control, rest, and analgesics for pain control. Our case describes a 42-year-old male with uncontrolled diabetes who presented with four weeks of progressively worsening right-sided lower extremity pain. The patient was taken to the operating room for concern for necrotizing fasciitis; however, it was ultimately ruled out. A diagnosis of diabetic myonecrosis was made. Recommendations were given for strict blood sugar control and to start aspirin 81 mg daily. The patient was later seen in the outpatient clinic with improvement in the lower extremity pain.
