question: Last month I saw the doctor about feeling pins and needles throughout my head, blurred vision.  No pain, just annoying feeling.  Had a MRI which was negative.  MRI negative for tumors appeared normal.  Ordered to stop Crestor see if that was the cause.  Pins and needles went away after three days but now I can feel my pulse throughout my head.  Good B/P 120/68. Blood sugar around 160.  Labs are all normal.  Where to now?
