Vasculare ES, could cause some scary symptoms and can in some cases cause TIA short for transient ischemic attack. If your arteries/veins are obstructed it will affect the blood flow and can become clogged. The arteries/veins around your neck goes up to your brain and serves your brain with oxygen and nutrients, lack off this can cause brainfog and fatigue.
I would suggest you get a utlrasound scan to rule out possible vasculare issues, or at least discuss that with Dr. Martini.
