My friends sister has the exact same thing. She was diagnosed with MS. Her MRI confired the diagnosis of MS. IT also showed a portion of her brain is growing into her spinal cord. The doctor said this had nothing to do with the MS. Another friend of mine who does not have MS had her brain growing into her spinal cord. HEr husband saw a show on TV and then looked at her MRI and he saw she had it. All of the doctors and radiologists had missed it. She had surgery to correct the problem. She is now back to work full time and has no more dizziness. First, I think that you need to get a definive diagnosis for the MS. If you do not have it, then ask about the other problem. Good luck. She had her surgery in Philadelphia. If you need any more information, please e-mail me.
