I had something similar a few years ago ( I was under stress), but it was diagnosed as Bell's Palsy (the muscles on the right side of my face seemed to have gone dead). I could not close my right eye, knit my brow (right side), or smile on that side. It took three months of electric therapy and swallowing folic acid tablets to get it back to normal. As soon as possible, check if you have BELL'S PALSY - the longer you wait, the harder it will be to fix it, if this is what you have. Don't delay!
