9 months ago i suffered a very dramatic dizzy spell that lated 4 days, i couldnt eat or walk during this time, and it took me a further 3 weeks to b able to walk in a straight line, the docs kept saying i had virtigo, but i didnt believe that and kept going to my gp, till he agreed to an mri scan, where they found a large posterior fossa, the specialist said my symptoms have nothing to do with my cyst, i DISAGREE, my symptoms are, a massive 24 hour weird feeling, my balance is not great, and im starting to feel paranoia, and my vision is going down hill, the specialist said he was not going to give me treatment, can i chalange this???? i feel very strongly that my cyst is a problem, x
