2. Grinning
Grinning might sound like a nice thing, but the official description is ‘grotesque grinning’. The condition has even been called ‘the grinning death’. Not so nice now!
This of course is a result of the stiffness and tightness affecting the neck and jaw, so if your grin seems to be pulled across your face, then this is definitely a cause for alarm and you should seek a doctor as soon as possible for a shot.
