This might be helpful to some of you. For the last few months I have been suffering from dizziness, nausea, and ringing in my ears. I went to my primary doctor who found nothing and referred me to an Ear Nose and Throat specialist. He said it was not an inner ear problem and suggested I have an MRI. The MRI revealed I have Arnold Chiari Malformation of my skulll and brain stem which could be causing my symptoms. I am getting ready for surgery to fix it. Ask your Doctors to do an MRI and look specifically for Arnold Chiari Malformation. I was at the end of my rope and thought I was going crazy when I finally found out I had this malformation. I hope this helps you all!
