I am having my brain mri on thursday and starting to worry what will be found. I had a ct scan which showed 3 shadows. My head symptoms have been awful since november. I go dizzy everytime i lay down or get up, awful headaches and pressure, my eyes sometimes water, earache and nausea etc. I don't know what it could be but i am hoping it's not too serious. I know something is definitely going on because of the awful headaches.
