I woke up yesterday & my whole body feels like it's on pins & needles. i also have ringing in my ears & a bad head ache. any ideas what it could be?

Go to ER: You are describing a systemic problem with abnormalities in the central nervous system. It appears to be affecting your entire body. There are enough bothersome findings here for you to go to the emergency room for an evaluation and laboratory/imaging studies to make sure you aren't ignoring a real problem. I would recommend going soon- don't wait.
