A TikTok star with a “hulk” arm has left social media users in shock after revealing how doctors discovered her unusual condition – with the only clue a “small bruise”.

When Olivia Klopchin was just two months old, her family spotted a strange mark on the inside of her elbow, where it had been since birth.

She was soon diagnosed with vascular malformation – an abnormal development of blood vessels that can cause discolouration or protrusions in the affected region.

For Olivia, this also meant her arm and hand grew extremely large.

Now 19, the influencer, who has over half a million followers, has embraced her condition.

She recently took to social media to share the subtle early sign that something was amiss – with the video racking up over 1.4 million views.

“I’ve definitely had a lot of interesting reactions to my arm on the internet,” Olivia, who has previously hit the headlines for talking about day-to-day life with her condition, told http://NeedToKnow.co.uk .

“Some people are so awesome about it and tell me how beautiful I am and how much they love my confidence.

“But then there’s the negative people who try to tear me down and break my wall but there’s always going to be negative people on the internet – that’s something we can’t escape, whether we want to or not.

“Negativity on the internet has consumed so many people’s lives, but I choose not to let it consume mine.”

In the recent viral video, Olivia, who is from from Springfield, Vermont, US, reveals the sign that led to her diagnosis – with over 53,000 likes and plenty of comments from stunned users.

“Being born with a small bruise on my arm…,” she captioned the clip.

A person singing ‘How bad can it possibly be?’ is heard, followed by a cut to a video of Olivia posing with her hands on her hips, showing her vascular malformation.

One user said: “My jaw dropped.”

“That ain’t no bruise,” another person added.

Someone else said: “No wayyyyy.” [sic]

“EXCUSE ME,” another person added.

Other users have compared the influencer to the Hulk and Nik Naks crisps.

One person asked: "Do you at least have Hulk like superpowers in that arm?"

Olivia has also been inundated with comments asking her why she hasn’t had her fully-functioning arm amputated – something she has chosen not to do.

For the influencer, amputating her arm has never even been a question, though it has impacted her life.

She added: “I never had a rough time with it growing up.

“Of course, I got stares from people but I understood at a young age that I was different and that people were going to stare and that there was nothing I could do about it.

“With vascular malformations, there is pain because we do get blood clots and blood clots are formed from the veins not having a muscular wall around them so our veins expand and blood can’t flow through easily so it clots up – and blood clots can be very, very painful.

“Fortunately for myself I don’t get them as often as a lot of other people that I know with vascular malformations.

“I’d say I get three bad ones a year other than that I get a couple monthly but they’re not too painful.

“Other than pushing through the pain, I was able to do sports, I would hang out with friends, and my friends would question things about my arm but I was always open and willing to answer the questions they had.

“I am truly thankful that my arm hasn’t given me any downsides to life. I could consider the pain a downside but I choose not to.”
