Vital signs are within normal limits except for a slightly elevated temperature of 99.8 degrees Fahrenheit.  Laboratory results are pending, including a complete blood count (CBC) with differential, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) to assess for markers of infection.  Radiographic imaging of the right foot, including X-ray and potentially MRI, is ordered to evaluate for bony involvement and assess the extent of the infection.  Differential diagnoses include cellulitis, gout, and diabetic foot ulcer.  Preliminary diagnosis is osteomyelitis of the right foot.
