7-year-old boy is allergic to winter due to rare condition

He’s allergic to winter.

A 7-year-old boy from the United Kingdom has life-threatening allergic reactions to frigid weather due to a rare skin condition, according to a new report.

Tommy Leitch suffers from a rare disorder known as cold urticaria and angioedema, which leaves him with rashes, difficulty breathing and a swollen stomach during winter months, according to The Sun.

“Last winter he was hospitalised every month as his allergic reaction caused him to violently vomit, struggle to breathe and was delirious,” his mom, Abigail McDonald, told the outlet.

“It’s a horrific condition and I always panic about it as it can be life threatening if Tommy doesn’t get urgent medical attention.”

McDonald said Tommy’s symptoms began two years ago when she noticed a rash on his head.

“I thought it was just a viral infection but the next morning he was covered from head to toe and complaining of stomach and chest pains with a swollen face and stomach,” McDonald said.

Tommy was rushed to the hospital, where he was referred to a dermatologist who gave him the diagnosis, according to the report.

They have also since learned that he’s sensitive to hot weather as well.

“I had no idea people could be allergic to temperatures before Tommy, which I think makes it even more difficult,” his mom said.

He requires antihistamines to reduce the flare-ups, which can become deadly if untreated, according to the report.

“I am always on guard as we never know when it is going to happen which makes it even scarier,” McDonald said.
