question: Sally was 45 years old and had been exposed to a viral infection. She had been working too much, she put in 40 hours per week plus moonlighted another 20 hours at a part-time job . . . and then she had to deliver the QC Times morning newspaper for a full week for her 13 year old son who went to Washington, DC for 8th grade field trip.The week that she had to deliver the 4:30 am newspaper had a late spring snowstorm and there were blizzard conditions.  Sally had to trudge thru the snow and wind to deliver these papers before going home to get ready to go to work at her full-time job and be there by 6 am.  She worked 6 am-2:30 pm and from her full-time job went to a part-time evening job to work on the customer service line for pharmacy and physicians' office claims problems until 7 pm.After a week of doing triple duty she woke up on Saturday morning of that week with her head swimming . . . feeling nauseous, but she still went to work, thinking that it would go away . . . bad decision. . . because she could not leave the coatroom at work . . .could not walk without touching/holding on to the walls. . . every person she saw was in slow motion . . . with frames repeating . . . like a computer page that has text bleeding into text when it's slow.  She had to  leave . . .and somehow she managed to drive home, throwing up as she drove . . .She was admitted to the hospital observation unit . . . ER physician noted signs of nystagmus. They did a CT scan of the brain which was negative.  She was put in an observation bed for 24 hours . . . dark, quiet room, given massive doses of Antivert 25 mg . . . she slept for 24 hours . . . and it went away.  Although it took 6 months for her balance to return to normal.  Medical term for this condition?????????
