But it turns out it being seriously worried wasn’t extreme at all. Williams took their advice and saw a doctor. She learned that her bent nail was much more serious than she ever imagined. “I was rushed for blood tests and a chest X-ray. Two days later I got a phone call to go for a CT scan, two days later a PET scan and more blood tests, [a] day later a breathing test on my lungs and a scan on my heart, [a] day later an MRI scan then a lung biopsy,” she explained. “After a grueling two weeks, yesterday I got my results…….Cancer in both my lungs!!!” Of course, not every nail issue indicates a chronic illness. But if you notice distinct changes in the shape, color, or texture of your fingernails or toenails, it’s a good idea to go and get it checked out. “I have realized lately that one of my nails has been doing that. I just thought I must of been deficient in something and have been cutting my nails really short so it’s not noticeable. Might have to go see the doctor. Thank you so much for posting this,” one woman wrote. Posting a photo of your fingernail online might seem like a small or meaningless gesture to some, but in this case it truly could be the thing that saves someone else’s life.
