However shortly after setting out on the reasonably difficult stroll round Alderley Edge together with her husband, Lauren Layfield felt her legs starting to ‘itch like mad’.

Inside minutes, the feeling was so insufferable that the Capital radio presenter, 34, needed to cease the place she was, in a subject, tear off her denims and claw helplessly at her prickling limbs.

The issue was not the standard rural hazards, akin to nettle stings or insect bites — the acute itching had been set off by the sheer exertion of strolling.

The trigger, a little-known situation generally known as exercise-induced urticaria (or cholinergic urticaria), is surprisingly frequent. Round one particular person in 2,000 is affected, i.e. 33,000 or so Britons. Whereas anybody can develop it, it’s extra probably for those who even have eczema, bronchial asthma or different allergy symptoms.

Even delicate train could cause raised bumps and blotchy, purple, severely itchy pores and skin. Signs usually subside inside 15 to half-hour of stopping train.

‘It was simply terrible, I needed to strip off as a result of my legs felt like they have been on fireplace,’ remembers Lauren, who additionally experiences for The One Present on BBC1 and lives in London with husband Luke Beddows, 34, a comedy author.

Shortly after setting out on the moderately challenging walk around Alderley Edge with her husband, Lauren Layfield felt her legs beginning to ‘itch like mad’.

‘I used to be scratching like loopy. I needed to sit there till the itching calmed down after which creep again to the automobile at a snail’s tempo to cease it taking place once more.’

This was not the primary such assault for Lauren, however it was essentially the most extreme.

She started experiencing signs in her late teenagers. ‘If I went tenting with buddies or out for walks, I’d discover the tops of my legs begin to really feel itchy and the pores and skin would look purple and blotchy,’ she says.

‘It didn’t matter what I used to be sporting, it might simply occur. I used to be on the College of Lincoln on the time, learning drama. Being a pupil I didn’t do a lot train, however I started to make the connection that after I did some type of train the itching and flushing on my pores and skin would occur.’

Like with any allergic response, her set off — train — causes histamine and different chemical messengers to be launched.

These trigger the blood vessels to dilate (leading to redness or pinkness of the pores and skin), and leak (inflicting swelling and itchiness).

‘Cells in our pores and skin referred to as mast cells include histamine and, in individuals with cholinergic urticaria, train could make them “hyperactive”,’ explains Dr Sophie Farooque, an allergy marketing consultant at Imperial School Healthcare NHS Belief, and creator of Understanding Allergy.

Different elements akin to warmth, the solar’s UV rays and sweat may also play an element. In some instances, it’s the mixture of train and a sure meals that causes the response — so-called food-dependent exercise-induced anaphylaxis.

‘Some individuals with sure meals allergy symptoms might solely expertise a response after they train,’ explains Dr Farooque. ‘The train might be very mild, akin to going for a stroll or operating for a practice, and folks can react as much as 4 hours after consuming or sometimes longer.’

Meals usually implicated in food-dependent exercise-induced anaphylaxis are wheat and shellfish.

She began experiencing symptoms in her late teens. ‘If I went camping with friends or out for walks, I’d notice the tops of my legs start to feel itchy and the skin would look red and blotchy,’ she says. A file photo is used above

However because the response can happen hours after exercising and consuming, it may be troublesome to find out which meals is accountable.

Docs imagine the situation happens as a result of after we train, our cardiovascular system redistributes blood to our working muscle tissue, sending much less to different areas, such because the intestine.

‘This slows digestion and the meals sits within the intestine for longer, permitting higher absorption of the meals the particular person is allergic to and this triggers a response,’ says Dr Farooque.

Over time, Lauren’s situation worsened and the itching unfold to her abdomen, chest and up her neck throughout train.

On the age of 26, unable even to run for the bus to get to her job (on the BBC’s Media Metropolis in Manchester) for concern of an assault, Lauren determined to see a health care provider.

‘The itching was completely maddening,’ she says. ‘My pores and skin was purple and blotchy however it was the necessity to scratch that drove me completely loopy.

‘This was taking place daily. It actually started to have an effect on my life. I didn’t do any train, save a little bit of weightlifting on the fitness center.

‘And I finished sporting sure garments akin to skinny denims as a result of it made it worse. Each single day I used to assume, “how am I going to plan my day to keep away from these flare-ups taking place?” ’

Her GP was baffled and referred Lauren to an allergy specialist, who identified her on the spot.

‘I laughed after I was informed,’ she remembers. ‘I knew my pores and skin was reacting to bodily exercise however I by no means realised it was an precise factor.

‘It sounded ridiculous. Nonetheless, I used to be additionally relieved that I wasn’t simply imagining it.’

To verify the analysis, Lauren had a blood check and ran laps across the hospital automobile park, and up and down stairs to see what occurred to her pores and skin.

After ten minutes, not solely was her physique coated in blotches however her pupils have been dilated — an early signal of anaphylaxis, a extreme allergic response which causes the immune system to launch a flood of chemical substances that may trigger a sudden drop in blood strain and blocking of the airways, making respiration troublesome.

Folks with cholinergic urticaria who proceed bodily exercise with out taking antihistamines threat this doubtlessly deadly complication. ‘I realised for the primary time that this situation had the capability to be fairly harmful if not managed correctly,’ says Lauren. ‘It was terrifying.’

Controlling cholinergic urticaria contains taking antihistamines frequently, or at the least an hour earlier than train to forestall a response, says Dr Farooque — and in the event that they develop a rash, these affected ought to cease exercising instantly. For some, stopping exercising or exercising in a cooler a part of the day will likely be sufficient to scale back or cease signs.

Lauren now takes robust antihistamines and carries an EpiPen in case of a extreme allergic response. She has not but had to make use of it.

On this routine, Lauren can handle her situation, although she avoids operating, taking part in sport or strolling too rapidly for concern of an assault. There’s a lot of issues Lauren would like to do however can’t due to her situation.

‘I’m usually requested to run the London Marathon and different races for charity and I might like to say sure however I can’t threat it,’ she says.

‘I’m simply grateful I’ve discovered a method to management the terrible itching and realise what I have to do to remain protected.’
