I was bitten by a false widow spider while I slept and left with stomach-turning injuries

And horrifying footage taken shows how her brave sister Natalie Ward was later forced to help squeeze out the infected pus.

It was only on her third trip to hospital that Kayleigh said she finally found out she had been bitten by a spider believed to be a false widow.

She believes it sneaked in through her bedroom window and is still fearful it is loose in her house.

Kayleigh said: "I woke up with the lump in my arm. It was probably the size of a golf ball. I think I was asleep when it happened. I don't sleep with my window open. I just open it in the day for an hour or two to let some air in.

"I haven't found the spider which is why I've been sleeping wrapped up in a duvet. I've never been worried about anything like that until this bite.

"My arm was humungous. It started just under a golf ball and I reckon it got three times bigger."

After first waking up with a red arm, Kayleigh went to work at the weekend and drew a line around the infected wound.

She continued: "I went to work on the Saturday and drew a line around my arm to see if it spread.

"I then went to the hospital to A&E and they took some blood tests. I was there for about seven hours and didn't see a doctor because it was about 5.30am.

"They booked me an appointment on the Sunday where they gave me antibiotics and said if it got bigger to go back. There was a redness that went all around my arm and the size of my arm tripled by Sunday.

"I went to hospital two or three times. There wasn't an entry wound where the spider had bitten me until Sunday. When I went back again [on Monday], that's when the lady said it was a bite from a spider. I reckon it was a false widow spider bite.

"It's infected and just to make it worse, I'm type one diabetic. That's why I went to the hospital so many times. I was worrying at first because they didn't tell me what it was until the Monday."

Kayleigh then found herself in even more pain the very next morning.

It was so bad that the bite victim begged her sister to squeeze out the fluid that had already begun seeping from her arm.

Kayleigh said: "In the end, I put a hot water bottle on it to bring it to the surface. The following morning when I touched it, it was seeping for about half an hour.

"When I woke in the morning my other sister, Mia, asked me how my arm was. All I did was touch it to show her and as I touch it [pus] started to come out of my arm, so you can imagine how full it was."

The restaurant manager adds how her arm "throbbed" as the wound oozed with pus when selfless sister Natalie Ward, 24, squeezed it.

She continued: "[Natalie] was squeezing it for me in the video. I wanted to try and get everything out. It was oozing the pus for about half an hour. It was huge. After that, it wasn't as full so it didn't hurt as much.

"It was throbbing until all the stuff [pus] came out. I still have it on my arm almost a week later. I wear dresses at work and it's not nice to have a big lump on my arm."

Dubbed one of Britain's most dangerous critters, the false widow spider comes with a venomous bite capable of causing a severe allergic reaction in some people.

Normally, the false widow's bite is similar to a wasp or bee sting, and it’s not usually fatal but some have come down with horror injuries.

It comes as a gardener shared his shock after being bitten by a false widow on the hand.

While another man had the back of his hand removed and was days from death after a false widow bite caused sepsis.
