A 49-year-old woman filmed herself having a stroke on her smartphone after doctors told her she was suffering from stress.
After suffering numbness and tingling down the left side of her body at home in Toronto, Stacey Yepes went to doctors suspecting she had suffered a stroke.
They, however, told her it was stress-related.
"It's true that I hadn't slept well the last few days and that I have a stressful job," said Yepes, who works as a legal secretary," she said. "But I was pretty sure that the symptoms I had experienced were due to a stroke."

However, only two days later it happened again in her car - at which point she decided to start filming herself.
The footage was later shown to doctors at Toronto Western Hospital, who confirmed Stacey's self-diagnosis that the attack was indeed a transient ischemic attack (TIA) or mini-stroke.
TIAs are seen as indicators that a more serious stroke could happen, and Stacey was referred to a stroke unit at the hospital.
The Stroke Association says the symptoms of the conditions can be recognised using the following identifiers:
Facial weakness: Can the person smile? Has their mouth or eye drooped?
Arm weakness: Can the person raise both arms?
Speech Problems: Can the person speak clearly and understand what you say?
If the victim fails any of the above tests then help should be sought immediately by dialling 999.
