I am a 33 year old mom of 3. I have been diagnosed with Hashimoto's Disease some years ago and take Synthroid for it. I seem to be healthy. I have had a concern about my vision here lately, though. Can spine misalignment cause vision that "shakes?" If I look at lines that are close together, they seem to quiver, almost vibrate. This can be stripes, patterns, lights lining a sidewalk, anything. It's like they jump, or shake...it's weird. I've been unsteady, I guess dizzy feeling...sometimes I have a headache with it, sometimes not. The headache is usually on top of my head. My question is, I have an appointment with a chiropractor tomorrow for a spinal alignment...could this be a reason for the shaky vision?
