When you notice something a little off about your body, there’s two things that could happen: You might overthink it, or you might not think twice about it.

There’s a fine line of when people actually think hey should go see a doctor. Some people go for any little thing out of the ordinary, and some people ignore it until it’s too late.

You obviously don’t want to put your health in jeopardy, but you also don’t want to be the boy who cried wolf and have the doctor know you by name, rolling their eyes every time you come in.

Then there’s the whole “don’t diagnose yourself online!” thing. One of the first things people do when they feel off or notice something weird is to Google it and figure out what could be going on.

This gets a bad rep because most of the time it’ll tell you something much more extreme than what’s going on. Like if your toe hurts, you automatically have some kind of fatal disease.

And sometimes, that’s wrong. But what if it’s right? What do you do when you notice something weird is going on, you research it online, and it tells you that you have cancer? Are you supposed to ignore it because the thing you researched doesn’t seem like that big of a deal, even though there seems to be evidence telling you that your health is in danger?

One 53-year-old woman from the UK named Jean Williams Taylor began to notice that some of her fingernails were starting to curve.

She didn’t think there was anything wrong with her health, she was just concerned that they didn’t look great and wondered if anyone she knew experienced the same thing. So she took to Facebook. She posted a photo of one of her curved nails and asked if it was normal.

It was Taylor’s daughter who began to research bent fingernails and found that it could actually be an early sign of heart or lung disease. So she urged her mom to pay a visit to the doctor. But Taylor felt silly about it.

“I didn’t want to go to the doctor over a curved nail, but I did it to put my daughter’s mind at rest,” Taylor said. “She’s the Google queen, and when you Google it the first thing that comes up in big bold letters is cancer. I felt ridiculous going to the doctor over a curved nail. I just thought I was wasting their time.”

But it actually wasn’t a waste of time at all. Doctors performed x-rays, blood tests, MRI and CT scans, the works.  Two weeks later, Taylor found out she had stage 1 lung cancer in both of her lungs.

Taylor posted the photo to her Facebook explaining what had happened, in hopes to help out anyone else who might have experienced the same thing.

“When your nails curve its often linked to heart and lung disease and its official term is ‘clubbing.’ I had no idea…did you???? Hope this post can help someone else in the early stages of cancer,” she wrote.

Moral of the story: See a doctor if you think something is wrong—chances are, if you think something is off, it is, even if it seems ridiculous. Your health is important!

Have you heard of or seen “nail clubbing” before? Did you have any idea this could be the link to something so detrimental?
