Hi. I m just very concerned about my 29 year-old daughter who recently had vertigo so badly that she couldn t walk for 9 days. She was unable to lift her head without vomiting and had a loss of peripheral vision. She went to urgent care, and they did blood work that came back normal with the exception of high glucose, low protein and zinc. I have MS and am concerned she may too. She also has a 1/2 brother with a brain tumor. Should I insist she at least get an MRI of the brain?
