My 26 year old daughter developed sudden dizziness, some episodes of syncope , and seeing black spots in her left eye or poor vision in her left eye 6 days ago. These symptoms cont to occur, with episodes of them getting worse and then just feeling dizzy all the time. She has had a CBC, Chem panel, thyroid check which were all normal. Her Vital signs are within normal limits. Her head CT showed possible areas of white and gray matter merging-she was told she could have Multiple sclerosis and is having an MRI on Friday and seeing a neurologist next Wednesday. She is not on any medications. Should we be taking her back to the ED and what might be the possible causes. SHe does not have a headache.
