A mother has cautioned Brits to seek immediate medical assistance if bitten by spider.

Delyth Hughes was sitting by her father in his tractor on the family farm in Flintshire, Wales, when she felt something crawling on her leg.

She didn’t realize she’d been bitten by a false widow spider until hours later, when she became queasy and disoriented and noticed two tiny puncture wounds.

She lost sensation in her leg and began to experience constant pins and needles in the days that followed.

Worse yet, the bite became bruised and bloated as it filled with pus.

Friends and relatives advised the 29-year-old, who has two children, to seek medical attention, and she told she’s “happy” she did.

“It would have ended differently for me if the poison had travelled through my body,” Delyth, who lives in Denbighshire, added.

Despite neither experiencing a bite nor seeing a spider, her leg became “very painful” following her visit to the farm.

“It was aching heavily and I started feeling nauseated.” “I had a severe headache and was having dizzy episodes,” she explained.

She then discovered two little puncture wounds and bruises.
