Suffering With Loss Of Balance And Constant Back Pain. MRI Showing Arnold Chiari Malformation. Should I Be Worried?

Question: hi I have been in hospital for the past 4 days I have for many years suffered with loss of balance, clumsiness, dizzy spells, blurred vision, and the past 4 yrs have now also included constant lower back pain, severe headaches, sickness and sometimes problems swallowing, the other day I went to bed fine but in the morning I woke up and could not focus my eyes, I had blurred vision and was walking like a drunk, I went to the doctor who refered me to hospital straight away and I was admitted for mri and ct scans. The MRI showed up that I had type 1 Arnold chiari malformation, the rhombergs test came up positive on right side. the next day I was told I don't have Arnold chiari malformation, that I have vestibolopathy. they did more tests and I was released today and my release notes say mri scan positive for mild inferior migration of cerebellar tonsils indictive of chiari 1 malformation. and to follow up with doctor and nureologist in 2 weeks and have been given pain relieve medication and anti sickness tablets. im confused, what is my diagnosis? can you enlighten me please. forgot to mention, I have also been getting constant ringing noise in my head since this most recent episode and tingling in my finger tips, even though I have been released from the hospital I am finding it very difficult to walk properly (straight), and unstable with my balance, focus and vision still blurry, this is my worst episode ever and the closest I have ever come to a diagnosis. but now confused about the results
