You can’t smile straight
If the face staring back at you in the mirror doesn’t seem like yours, or you can’t seem to make it move like you want it to, it could be a stroke. A drooping face—numbness or paralysis on one side—means part of your brain isn’t getting enough blood. “Often, somebody might tell me their face feels swollen, or they’ll drool out one side of their mouth” because they have difficulty swallowing, says Modir. If you grin and one side of your mouth stays down, something’s up.
