Gosh the brain and spine problems always seem to cause similar problems. I have severe DDD in cervical and lumbar spine and do not have any offered treatment aside from physio or injections. Physio is good but the injections did nothing. My carotid arteries have minimal blockage but I have a tortuous vertebral basilar artery. Doctors brush that off as nothing, but I suspect otherwise as I can early pass out if my head is in certain position. Maybe a doppler ultrasound would show something. Lack of oxygen may have caused my lacunar infarcts as well. Still guessing there.
