In the "Heat index," the selfie that may have saved a woman's life. Doctors didn't believe anything was wrong so she shot a video of her face when she experienced paralysis on her left side and that helped diagnose the problem. Mara schiavocampo has that story for us. It was like 6:42 and sensations happening again. Reporter: Some quick thinking. It's all tingling on left side. Reporter: And this cell phone video -- I don't know why this is happening to me. Reporter: May have saved this woman's life. 49-year-old Stacy jepis was driving home after running errands when she felt half her body go weak. The smile, they said, smile. My hand is hard to lift up. Reporter: It was panic. It was fear because my leg, my arm, my face, my speech, everything. Reporter: But this wasn't the first time this happened. Just two days earlier Stacy was watching TV when her entire left side went limp. She rushed to the emergency room where doctors gave her a diagnosis she couldn't believe. Stress. I really thought to myself you're kidding me. Reporter: Doctors told her if the weird symptoms happen again just breathe. So when the numbness and slurred speech came back, she did. The doctor said to breathe in, breathe out. Managing stress. Reporter: Whipping out her smartphone to document her episode. Then I just pulled out my phone because I needed somebody to see what was happening to me. Reporter: Less than 48 hours later she showed the video to doctors at krembil neurocenter. This time she was diagnosed with a small stroke called a tia. Hard to describe. Videotaping gave us a compelling picture of what happened to her. Reporter: Had she ignored the symptoms she would have likely had more strokes putting her at risk for permanent damage. Today she's getting rehab treatment and taking medication to prevent another episode and, of course, her phone is now always at her side. Now I don't leave home without it. I will dial 911 first and, you know, it's always handy just in case. For "Good morning America," Mara schiavocampo, ABC news, new York. Thank you, Mara. Bringing back rich Besser. Call 911 first. Yes. The fact that she did this. Are more and more people doing it? I mean, this is extremely rare. If you're having one of these it's a frightening experience but think back five years ago. People didn't have a video camera with them but it can provide incredibly useful information much as a pediatrician, I'm frequently saying to parents, you know, why don't you film that. They'll say my child is making a strange noise when she's sleeping at night. Get it on film. A rash that comes and goes. It can be so incredibly helpful and here in this case it probably saved her life. 10% of people who have this will have a stroke within two days, a real stroke. What's terrifying she was being misdiagnosed even brushed off a little bit. What do you do if that happens? Doctors make mistakes. If you're having a panic attack and hyper vent late the symptoms can look a lot like this. It can help if you have an advocate, someone who can describe that she wasn't panicked. It came on suddenly. Ask for a second opinion. If they brush you off and you're not feeling you're getting good care the next day go see a specialist on that and then document everything that happens, all of your symptoms so that when you go, you can say it was this, this and this. I was just sitting this and it came on. What are the symptoms of an actual stroke so you can know if you're in serious danger. The first thing is, realize that young people can have strokes. More than 600,000 younger than 45 have a stroke every year. Remember F.A.S.T., "F" for your face, facial droop. "A" for arm, if one droops, weaker, that's a sign. "S" for slurred speech and "T" for time because every second coups. You have those, get to the emergency room. Get there right away and tell them what happened and they'll do studies. If you're having one of these, your scans may all be Normal. You'll have to go back again and again.
