Facial tightness (Side and top of head )

Hi everyone just wondering if anyone can help.im on mirapexin 1-57 mg once a day.i ve had a sudden numbness come on one side of my face.it started in right ear then spread within seconds up the right side of my face and at the top of my head.it comes and goes and you can feel it moving.when it happened I thought I was having a stroke.is this to do with involuntary muscle movement I don't know.but it is horrible and feels like a pressure on you all the time.anyone know anything.twins99
