(CNN) -- It's not your usual selfie.
"The sensation is happening again," Stacey Yepes tells the camera. "It's all tingling on left side."
"I don't know why this is happening to me."
The Toronto-area woman was having her third stroke in three days. And this time, she refused to suffer in private, according to CNN.
Yepes recorded a selfie video of her symptoms after pulling over while driving. The next day, the video would help doctors at Toronto Western Hospital correctly diagnose her with transient ischemic attacks, or "mini-strokes," due to plaque buildup in her arteries.
Now, according to Yepes, she is on cholesterol-lowering medication and blood thinners, and hasn't had any more strokes.
The video may have saved her life.
