dr. Karan Rajan (pictured), a surgical doctor and a lecturer at Sunderland University, informed his 4.2 million TikTok followers about how the texture and appearance of a person’s nails can be indicative of various conditions
At the beginning of his clip, he said, “If you’ve noticed these cloudy white spots on your nail, they’re common and normal. It can also be caused by physical injury to the nail.’
However, he warned viewers about a dark streak on their nails that has been there for a while and seems to be growing in size.
What do YOUR fingernails say about your health?
dr. Karan Rajan revealed how the texture and appearance of one’s nails can indicate various conditions:
1. Dark streak may be linked to cancer
2. Yellow Spots Indicate a Yeast Infection
3. Cracked Fingernails Indicate Nutritional Deficiencies
4. Cloudy White Spots Likely Caused by Physical Injury
5. Small Craters Are ‘Usually Caused by Psoriasis, Arthritis, or Eczema’
If it wasn’t caused by an injury, it could be a rare cancer known as subungual melanoma, a serious form of skin cancer that occurs in the skin under your nails.
He went on to talk about small craters that sometimes appear on spikes and look like “someone brought an ice pick to them.”
“This is called pitting and is usually caused by psoriasis, arthritis or eczema,” he said.
He also explained why your nails can turn yellow, suggesting it could be a fungal infection known as onychomycosis, or tobacco from smoking.
If your nails are cracking and flaking, it could be brittle nails, which Dr. Rangrajan attributed it to some nutritional deficiencies and urged viewers to follow a varied diet.
Since the video was posted, it has received more than 760,000 likes and comments from users who said they were unaware of these issues.
However, many have pointed out that a dark line running through your nails is a common occurrence among dark-skinned people.
One person said, “I have the second one, but my doctor said it was melanonychia (a brown or black pigmentation of the nail unit), which is extremely common in dark-skinned people.”

Another added: ‘He forgot to mention that black line is quite common in Asian and African people and is usually harmless.’
Many feared they would suffer from a rare form of skin cancer, and one of them said, “No, don’t scare me, I’ve got that black thing on my thumbnail and it’s been there for a long time.”
Another joked: ‘I’ve had a black streak on my nail for years. We’ll see you at my funeral.’
