A woman says she looked like an "alien" and started hallucinating after suffering severe sunburn on her legs."

Cas Flynn-Troy, 22, became severely sunburnt after sitting out in the 24 degree heat at Beyond The Valley festival in Victoria, Australia.

The boxing and pilates teacher had been in the sun all day on December 31 - topping herself up with sun cream a few times throughout the day.

She noticed her legs had started to feel "hot" and went to the medical tent when she start hallucinating and realised her legs had turned "bright red"."

Cas was given painkillers to help her sleep that evening and cold water was poured over her legs.

But when she returned home the next day she felt exhausted and noticed blisters appearing.

She went to Royal Melbourne Hospital on January 2, 2024, and had the blisters drained and is now back home recovering.

Cas, who also works in marketing, from Victoria, Melbourne, Australia, said: "It felt like an alien was on my legs."

"It was horrible."

"It was so ugly. The blisters were huge."

"It was the worst pain I've ever experienced."

Cas was enjoying her last day at the festival with her friends before her sunburn developed.

She said: "We started sitting outside in our pyjamas."

"We put on sunscreen at the beginning of the day and reapplied a couple of times - but clearly not enough."

"We went into the festival at 3.30pm, saw some acts and then came out to eat."

"I put on trousers and noticed my legs were a little sore - but I'd been dancing for three days straight."

Cas went on to enjoy the rest of New Year's Eve but started to hallucinate and feel a pain in her legs.

She said: "I remember thinking 'why are my legs hurting?'"

"They just felt hot and they were swollen."

"I was holding the material of my trousers away. My legs were tender."

Cas got back to her tent before rolling up her trousers and seeing her red legs.

She said: "My legs were bright red."

Cas decided to go and see the medic at the festival.

She said: "The medic poured cold water over my legs and gave me painkillers."

Cas got back to home the next day and felt exhausted.

She said: "Blisters started growing. I was so exhausted."

The following day her family encouraged her to go to hospital.

Cas said: "They drained the blisters."

She came home after a few hours and has been resting her legs since.

She said: "It's peeling now."

"I wouldn't think this could happen. People say you don't burn your legs."

Cas now has four suncreams with her at all times and is still careful to cover her legs.

She said: "Check the UV rays - even if it's raining."

"Even if you tan it's still damaging your skin."
