I have been experiencing episodes where while standing my leg muscles freeze up to the point that I cant move them and have to be almost dragged to a chair, I can't raise my arms or barely open and close my hands, my face muscles are hard to move and my speech is slurred all of this happens at the same time. I thought that I was having a stroke the 1st time because of the paralysis but I didn't really feel pain. The doctors can never find anything wrong and all my blood work comes back normal so I get sent home with a take it easy and rest but I am getting no where and I know something is wrong.
