Hi, I'm a WF, 38, 5'11", 170 lbs. I have been experiencing continuous ringing in my ears, staggering gait, vision issues, fatigue, "pins and needles" pain in my extremities and loss of memory/ability to stay organized. I went to my ENT and he sent me to get an MRI. The reading said "3 mm focus of gliosis within the subcortical white matter of the superior frontal lobe. This is non-specific and could be secondary to chronic microvascular ischemia, previous trauma, demyelinating disease, chronic migraine headaches or vasculitis". What does this mean??
