Hi I had Botox in my frown line 7 weeks ago. The frown wasn't that deep on resting it just looked like a line, I now can't frown completely but my forehead doesn't look any different. I noticed recently I've had a headache I've massaged the area around the frown to relieve the pain and the area goes immediately numb and strange feeling and when I look into the mirror the area is distorted as though it's stuck in a trapped nerve position. It goes back to normal within a minute but what's happening here?
