A 35-year-old African American female (AAF) with a past medical history (PMH) of mutliple sclerosis (MS) is admitted with a chief complaint of generalized weakness and inability to walk. At baseline, she is able to transfer independently from a bed to a chair and to walk with assistance. Her PMH is positive for urinary incontinence and frequent urinary tract infections (UTIs) that lead to MS flares. The current complaints are typical of her MS flares.
She also complains of (c/o) nausea and has vomited in the emergency room (ER). She reports no abdominal pain or dysuria.
