I've been feeling a bit dizzy for about a month now. My brain feels like there's cotton in it. I just stare blankly my computer, my newspaper, whatever. Has anyone had these symptoms? Could it be part of a bad case of fibro fog? I've been diagnosed with a narrowing of the spinal column in my neck and am waiting for an MRI next week. I wonder if it could be that. I tried increasing my Synthroid (underactive thyroid)dosage for 10 days and these awful symptoms disappeared. I'm about to call my doctor, but don't want to seem an idiot if there's nothing that can be done.
