Nicola Peate – who has hyper-flexible joints – ended up in hospital after her chops locked around the meaty feast while on a night out with her work colleagues in Liverpool, north west England, and a doctor was forced snap it back into place.
The 25 year old was left in excoriating pain following the munching disaster and has now been advised to cut up her food and avoid opening her jaw too much.
Speaking to the Liverpool Echo newspaper, she said: “I didn’t think I’d dislocated it – you don’t expect it to happen eating a burger.
“I couldn’t open my mouth fully. It felt like I had cramp in my tongue, then I started to get an ear ache and a headache.
“The next morning I woke up and felt really, really ill. The whole side of my head was hurting.
“Then it started to feel like it was in my jaw and I knew I’d dislocated it.”
