In 2010, I was down for four months with excruciating and unexplained head "heaviness" (like a bowling ball swinging back and forth in the back of my head) that kept me from sleeping, walking, eating, etc. I also had severe sound sensitivity, ear ringing, and shaky vision. Several ER trips, a hospital stay with MRI and lumbar punctures yielded nothing. The Mayo Clinic in Arizona accepted my case and after spending over a week there having every tesr imaginable (more MRIs, lumbar punctures, evoked potential test, autoimmune panels), they could find no diagnosis. I thought I was dying. I then was given Klonopin to help manage my anxiety and it seemed to all of a sudden help my head-swinging symptom and sound sensitivity. I took Klonopin for about a month and most of my symptoms eventually subsided in that time.
In 2012, I had another MRI done. No lesions showed up.
Recently, the shaky vision started again. The head-swinging has also returned (although much less severe), the ear ringing, and the pins and needles in my arms/legs. I'm scheduled for another MRI next week.
Does anyone know how many MRIs may be "clear," on average, before lesions start to show up? I had at least 3-4 MRIs from 2010-2012, and nothing.
I don't know what else might be causing all these symptoms.
