You respond to the residence of a 78 -year-oid male patient complaining of left flank pain that has been increasing over the past several days. Upon arrival, you are directed to a bedroom where your patient is lying in bed in a semi-sitting position, while your partner starts taking vital signs the patient tells you that he has no symptoms other than the severe local pain and some small skin ulcerations in the same area. Your partner tells you that his vitals are normai and abdominal exam is unremarkable other than the small blisters, which you then inspect. Which of the questions would best assist you in finalizing a field diagnosis? Are you allergic to anything? Have you ever had monasles? Have you ever had chicken pox? Do you have a history of psoriasis?
