Sydney Allen from Clearwater, Florida, had got the piercing discreetly done in June, but she was surprised when they showed up on a routine X-ray - which she had dragged her mum along to for moral support.

Sydney, 20, told Buzzfeed News: ''My mom saw my piercings as soon as the X-ray popped up and the doctor and I started laughing hysterically.''

Her mum - who she claims is ''a bit conservative on appearances and hates tattoos and piercings'' - initially didn't take it too well, saying: ''We will discuss it later.''

The has already gone viral and has helped to raise awareness of syringomyelia - a rare condition caused by fluid build up on the spinal chord that Sydney has regular checkups for.
