Since we last communicated I have had a MRA and an MRV. Below is the abnormal result that the MRV showed. The vascular Dr., that I saw later, speculated that I had probably always been this way. He could not explain the niacin flush experiences. What are you thoughts on the below MRV results?
I do have pulsatile tinnitus.Findings:
Diminished flow in the left transverse sinus, sigmoid sinus, and cavernous sinus compared with the right. This is suspicious for partial venous sinus obstruction or venous sinus thrombosis. This finding can be seen in patients with intracranial hypertension and chronic pulsatile tinnitus. The remainder of the exam is unremarkable.
Venous sinus stenosis or partial obstruction of the left cavernous sinus, transverse sinus, and sigmoid sinus compared with the right.
CFS pressure was normal.
I am the person who gets the light head pressure when upright and sees great symptom relief (including head pressure relief) during the niacin flush and, to a lesser extent, during and for a few hours after, magnesium foot soaks.
Sorry, that I kept adding to this - I kept thinking of more info and had noticed a few mistakes.
