Doctors have warned that a viral hack to stop your arm from hurting after getting the coronavirus vaccine may not be as effective as you'd hope. You can see the little trick here:
A bizarre TikTok trend has claimed that spinning your arm in a windmill-type motion can help to alleviate the sore arm some people have been left with after receiving their Covid-19 jab.
Many TikTok users have insisted it works and say they've experienced no pain after giving the arm swinging a go.
But experts have said that while the trick won't do you any harm, there's no proof it'll work, either.
Beate Kampmann, professor of paediatric infection and immunity and director of the Vaccine Centre at the London School of Hygiene & Tropical Medicine told The Guardian: "It's harmless, looks very silly and won't do anything.
"The sore arm does not actually happen immediately as the immune response has not yet happened, and not everyone gets it either."
And then to add insult to injury, Professor Kampmann added: "Let people wave their arms if it makes anyone feel better - it really is a tiny quick injection on the day.
"We give vaccines to children all the time and they are just fine."
Meanwhile, Adam Finn, professor of paediatrics at the University of Bristol and an honorary consultant at the Bristol Royal Hospital for Children, backed up Professor Kampmann.
However, he did go on to to say it could offer a 'placebo effect', which might make those who do it feel better, in a way.
He told the news outlet: "I doubt it is harmful - or helpful beyond any placebo effect, which could be substantial."
Professor Azeem Majeed of Imperial College London reckons the viral videos could be useful in boosting uptake rates of the vaccine - particularly in younger people.
He told The Guardian: "If it raises awareness of the jab and makes it seem like a joyful, playful thing, then that's a very good outcome to the dance."
A spokesperson from AstraZeneca said they were 'certainly not aware' of it being helpful.
Pfizer and Johnson & Johnson both declined to comment as the companies believed not enough scientific evidence about the viral trend was available.
If you do have a sore arm after your vaccine, your best bet is probably to take a painkiller. As well as being proven to tackle pain, it will also mean you don't look like a bit of an idiot.
