Since June 2008 I have been having episodes of numbness in my face, slurred speech, loss of words, confusion, numbness in my right arm, inability to control or use my arm but can feel it, same with my right leg, unable to walk and control my right leg. Not all symptoms always present at the same time, sometimes just the speech, sometimes just the leg or arm. These episodes last anywhere from 15 minutes to longest 1 1/2 hours.
