Meet the personal trainer who only sweats on one side of her body due to a rare condition - which can prompt questions from clients.<br /><br />Sarah Burford, 34, developed Harlequin syndrome after having a benign tumour removed in 2015. <br /><br />Surgeons also removed sweat glands in the top left corner of her body, giving her the issue.<br /><br />Sarah, from Gloucester, says she often gets questions from clients during workouts.<br /><br />And while she was initially embarrassed, she now recognises that the condition just makes her "unique".<br /><br />Sarah, from Gloucester, said: "It's a really weird sensation when one side of your face is boiling and the other is freezing cold.<br /><br />"I obviously sweat a lot doing the job I do. Seeing clients reactions always makes me laugh."<br /><br />Sarah was concerned when she started experiencing rib pain in December 2015.<br /><br />She went to the hospital, and x-rays showed a ganglioneuroma, a benign tumour, growing near her rib cage. <br /><br />Surgeons deflated her lung to access her chest wall and remove the tumour.<br /><br />But they also had to remove the sweat glands in the top left corner of her body.<br /><br />Sarah was then diagnosed with Harlequin syndrome - an absence of sweating and flushing of skin on one side. <br /><br />She's been living with the condition for eight years and has grown used to the weird sensation of a sudden mixture of hot and cold.<br /><br />And she's not let if affect her livelihood.<br /><br />The mum-of-one said: "I'm a personal trainer and train six days a week, so sweating is a regular occurrence for me.<br /><br />"When I do lots of high-intensity workouts, the right side of my face gets boiling and sweaty, and the left side is completely untouched.<br /><br />"It's a strange sensation, but after eight years, I'm pretty used to it now.<br /><br />"When I'm on runs with clients they'll sometimes notice it, so I then have to explain the whole story behind it.<br /><br />"It's more prominent in my life than it would usually be because of my job, but I've learnt to embrace it - it makes me unique which is never a bad thing."
