A 56-year-old Man with a past medical history significant for lower back pain and GERD was admitted to the hospital for dizziness and laboratory abnormalities.

Five days prior to admission, the patient noted that he felt dizzy and unsure while walking. These symptoms persisted without change and he went to see his primary care doctor the day prior to admission. The patient was given meclizine for his dizziness and routine labs were drawn. He received a call from his doctor on the day of admission instructing him to be evaluated for an elevated serum calcium.
