My long and unfortunate journey of finding out what is wrong with me is coming close to 11 months now. I'm a 15 year old boy. It all started from last december (it is now october) when I started feeling dizzy when I stood up and my balance and coordination was growing very poor. I have to cling to the railing when going up and down stairs and I go very slow. Every time I stood up, I would be dizzy, and it got worse and worse over time. By april I would have to sit down wherever I was because I got severe tunnel vision, ringing and a throbbing pressure pain in my ears. In May it got so bad that I actually passed out in the middle of my hallway in my house. I have a constant ache in my neck, all the time. It's always sore and uncomfortable. I also have a headache almost every single day, and I have had a past of migraines. I had gone to an ENT (ear nose and throat doctor) initially in december who just told me i just had a cold that was lingering. A few months later when i passed out, i went to the pediatrician who then sent me to a neurologist. She ordered an MRI without contrast but told me that she couldn't really help me. The MRI showed that i had slighty low lying cerebellar tonsils, but it specifically said i do not have chiari malformation. After the neurologist sent me away, I went to a different ENT doctor. He ordered an ENG test for me which I took and my results were abnormal. It showed that there is an issue with my central balance, and something to do with vertigo. He told me i should go ahead with another MRI but this time with contrast. Once getting my MRI results, he told me I should go see an inner ear specialist. I didn't get to see the report of this MRI as i did for my first one. At the inner ear specialist yesterday, he told me that the serious thing to look at in my MRI was the low lying cerebellar tonsils and he has sent me to another neurologist and headache specialist to be seen. He told me that the risk of chiari malformation is too great to go unignored so he wants the expert opinion on it because it isn't his field. I haven't gone to the neurologist yet but I am worried. If my original MRI said I DONT have chiari malformation, how could I now? Can it develop between the time of both MRIs (about 3 months)? Or did the contrasted MRI show a more indepth image of it. I'm just looking for some answers. What is the treatment for chiari malformation? What could my issue be if it isnt that? Thank you.
